Riveter & Rivet Gun Guide: Hand, Lever, Pneumatic, Rivnut & How to Choose

A rivet gun (or riveter) is the tool that sets a rivet — pulling the mandrel of a blind/pop rivet to expand it on the back side of a workpiece, squeezing a solid rivet between dies, or threading-and-collapsing a rivnut (rivet nut) into a panel. Without the gun, the rivet is just a piece of metal; the gun is what makes the joint.

This guide decodes the five tool families — hand, lever/long-arm, pneumatic, cordless and rivnut — plus the aviation specialty class. It covers the forum-validated brand reality, how to fix a mandrel jam, why a rivnut spins when you try to remove it, the production-volume thresholds that decide hand vs cordless, and the Australian supply position at the trade tier.

For the fasteners themselves see our Types of Rivets Guide and Rivet Nut Guide. This article is the tool-side companion.

What is a rivet gun and what is it used for?

A rivet gun is a hand or power tool that sets a rivet into a hole drilled through two or more materials, creating a permanent mechanical fastening. The rivet body fills the hole, and the head (or formed back-side bulge) clamps the materials together. Once set, a rivet cannot be backed out — removal means drilling the head off.

Typical jobs across Australian trades: sheet metal fabrication (ducting, roof flashings, gutters, downpipes), automotive panel repair (door skins, quarter panels, mudguards), trailer and ute body building, marine alloy hull work, aircraft maintenance (solid rivets — different tool class), signs and shopfitting, white-goods assembly, ladder and gantry repair, electrical enclosures, and HVAC duct lap joints.

The single advantage of riveting over screws: back-side access not required. Once the rivet is loaded in the gun, you only work the front face. That's why pop rivets dominate sheet metal trade — the back of an aircraft skin, a roof gutter or a closed structural section is often inaccessible.

AIMS stocks 17 rivet tools across Trax (10), Champion (6) and TTL (1) — see the full range at /collections/rivet-tools. For the rivets themselves, browse Types of Rivets.

Rivet types — the tool depends on the rivet

You choose the gun based on the rivet, not the other way around. Five rivet classes drive five tool families.

Most Australian workshop rivet work is blind/pop rivets plus rivnuts. This guide concentrates on those two with a clear scope note on aviation solid rivet guns (different product class, AIMS doesn't stock).

Hand rivet gun (short-arm) — the workshop entry point

The standard short-arm hand riveter is a two-handled tool with a head that takes interchangeable nose-piece nozzles for each rivet diameter. You squeeze the handles, the jaws grip the mandrel stem, the mandrel pulls and breaks, the rivet sets, the spent stem is ejected. Three or four squeezes per rivet on standard sizes.

Three things separate a quality hand riveter from a cheap one. Pull feel — quality jaws bite the mandrel cleanly and pull straight; cheap jaws slip and chew the stem. Jaw bite — premium tools have hardened tool-steel jaws that survive thousands of rivets; budget jaws round off in a few hundred. Mandrel clearance — the spent stem must drop out the back of the tool reliably; cheap tools jam every dozen rivets.

Standard short-arm hand riveters set rivets up to 4.8mm diameter in aluminium and 4mm in steel. Anything bigger needs a long-arm or lever-tong tool (next section). AIMS stocks Trax ARX-LR22 1/4" hand riveter, Trax ARX-HR01 3/16" hand riveter, Trax ARX-HR107 8mm 1/4" hand riveter and TTL BT106 standard (2.4–4.8mm workable range) at /collections/rivet-tools.

Lever / long-arm rivet gun — when force matters

Long-arm hand riveters have extended handles (250–400mm) that give a 3–4× mechanical advantage over short-arm tools. The same arm motion pulls a much harder mandrel break. Long-arm is the standard for the largest blind rivets (5/16", 6.4mm) and for steel and stainless rivets where pull force is high.

Champion stocks the long-arm class at AIMS — Champion CBRG-2 Long Arm Blind Rivet Gun (200mm+ arms) and Champion CBRG-1 Blind Rivet Hand Gun 200mm — see the full range at /collections/rivet-tools. Kincrome CL960 long-arm is the equivalent at Bunnings tier (not stocked at AIMS).

The trade-off: long-arm tools are heavier and slower per rivet, and they need clearance around the work for the long arm swing. For high-volume small-rivet work, short-arm is faster; for large rivets and harder materials, long-arm is the only hand option.

Lazy-tong / twin-handle rivet gun — biggest rivets by hand

Lazy-tong riveters use a scissoring mechanical linkage between the handles to deliver very high pull force in a compact tool. The "twin handle" name comes from the parallel handle motion. Kincrome Twin Handle Nut Riveter Set, POP PS25 Heavy Duty Lazy Tong Rivet Tool and similar tools live here.

Lazy-tong is the right pick for occasional 1/4" (6.4mm) blind rivets where you don't want a pneumatic compressor or a cordless platform investment. Slower per rivet than short-arm or pneumatic, but force-comparable to small pneumatic tools.

Pneumatic / air rivet gun — production-tier blind rivets

Pneumatic blind rivet guns use 90 psi shop air to do the mandrel pull automatically. Trigger pull → mandrel grips → pull stroke → rivet sets → stem ejects. One trigger pull, two seconds per rivet. The leap from hand to pneumatic is the single biggest productivity jump in riveting.

Air rivet guns shine in production sheet metal, trailer/body building, signs, and any workshop doing 100+ rivets per session. CFM demand is moderate (1.5–4 CFM at 90 psi for most tools) — a 30L+ workshop compressor handles them comfortably. See our Air Tools & Pneumatic Tool Guide for compressor sizing and the broader pneumatic tool range.

The forum-validated AU pro standard is Marson — Marson TT55D Industrial Pop Riveter is the most-quoted name across r/Tools, r/AusRenovation and AU supplier SERPs. Chicago Pneumatic is the global aerospace standard, used "for over 10 years" per r/aviationmaintenance. AIMS doesn't currently stock these in pneumatic — Champion and Trax in the hand-tool tier; specialty pneumatic on request.

Cordless rivet gun — the AU workshop reality

The cordless rivet gun has reshaped the trade in the last five years. Battery-powered tools with a mandrel collector cup pull a rivet in roughly one second, no air line, no compressor, no hand fatigue. The forum-validated quote from r/AusRenovation: "If it's a fairly frequent occurrence then a battery rivet gun with collector cup is your best option. Red, yellow, blue, orange brands all have..."

The brand landscape:

• Milwaukee M12 BPRT-0 — 12V cordless blind rivet tool. Popular but forum-flagged as slow: r/Tools direct quote: "I tried the Milwaukee M12 in the past, the thing was painfully slow."
• Milwaukee M18 FUEL 1/4" Blind Rivet Tool — 2024 successor, much faster. Production-grade.
• DeWalt DCF403 20V XR Brushless Riveter — r/Tools forum favourite: "DeWalt makes a 20v riveter for a reasonable price. I'm very impressed with mine."
• Makita 18V LXT Riveter — quiet, well-built, slower than DeWalt
• Metabo 18V NMP LTX BL M10 — German top-tier rivnut gun, premium specialty
• Ryobi One+ 18V, Ozito 18V — consumer-tier; OK for occasional use

Drill-attachment rivet adaptor — the slow shortcut

Drill attachments turn a standard cordless drill into a rivet tool — Kincrome Ezi-Riv KP45001 and similar. They work, but every forum review flags the speed issue. r/Tools direct: "Those drill ones are painfully slow. It'll take 10+ seconds to pull a rivet and reset the tool."

Drill attachments make sense for occasional use (50 rivets a year), or as a way to set rivnuts in a workshop that already has a quality cordless drill. For volume work they're a false economy — the cordless rivet tool above costs more but pays back in time saved within a few hundred rivets.

Rivnut tool / nut rivet gun — installing threaded inserts in thin panels

Rivnut tools (also called nutsert tools, nut rivet guns or blind rivet nut tools) install rivet nuts — threaded female fasteners that collapse into a panel from one side, leaving an M3–M12 metric thread for a screw. The tool screws into the rivnut, pulls it to collapse the body, then unscrews to leave the thread.

Five tool tiers exist:

The forum-validated production reality: r/Machinists thread on rivnut tools: "Make sure that the lever/plier style tool that uses just basic force is not the best for production use." Plier-style tools deform mandrels under heavy load — fine for occasional small rivnuts, but for daily M8–M10 production work the ratchet or pneumatic tier earns its place.

AIMS stocks Trax ARX-HRN2K Hand Blind Nut Riveter Kit (M3–M6) and Champion H2033-2 Nut Rivet Gun plus the Champion CRA-NR Nut Rivet Adaptor. For larger sizes or production-tier pneumatic/cordless rivnut guns, call (02) 9773 0122.

Aviation rivet gun — a different product class

Aviation rivet guns are not blind rivet guns. They are pneumatic hammer-style tools that drive solid rivets — the traditional aircraft skin fastener — by repeated impact while a bucking bar is held against the tail to form the shop head.

Aviation rivet guns are rated by force class: 2x for small rivets (-3, -4 nominal sizes), 3x for the standard range (the most common size), 4x for large structural rivets, up to 9x for the biggest. r/aviationmaintenance: "3x is the standard for most rivets. If you're going to be driving hard or large rivets, the 4x..." Trigger feathering — the operator's ability to vary impact rate — is a learned skill that separates aircraft sheet-metal workers from beginners.

Chicago Pneumatic is the global aerospace standard. Pan American Tool and US Industrial are specialty manufacturers. AU sheet metal trade doesn't use solid rivets — blind/pop dominates entirely. If you're not maintaining aircraft, you don't need an aviation rivet gun.

Rivet sizing — diameter, grip range and material

Three things have to match between rivet and tool.

Diameter — common blind rivet diameters in AU trade: 3.2mm (1/8"), 4.0mm (5/32"), 4.8mm (3/16"), 6.4mm (1/4"). The rivet gun ships with interchangeable nose pieces for each size; check the tool spec for max diameter (most hand riveters top out at 4.8mm aluminium / 4.0mm steel; lever or pneumatic for 6.4mm).

Grip range — the combined thickness of the materials being joined. Each rivet length covers a specified grip range printed on the box. Too short and the rivet won't fully expand on the back side; too long and the unfilled excess deforms. Always measure stack thickness and match grip range — the #1 cause of failed rivet joints.

Material — aluminium (the workshop default — soft, fast to set), steel (higher pull force, longer life in vibration), stainless (corrosion-critical, very high pull force), copper (electrical bonding), monel (marine extreme corrosion). Match rivet material to workpiece material to avoid galvanic corrosion.

How to use a pop rivet gun — 6-step procedure

1. Drill the hole. Drill the matched hole size through both materials (see table above — rivet diameter + 0.1mm typically). Hole alignment matters; clamp or jig if the parts move.
2. Select nose piece. Match nose-piece nozzle to rivet diameter. Most hand riveters ship with 3 or 4 nozzles. Hand-tight thread, then snug with a spanner.
3. Insert rivet. Push the rivet mandrel into the nose-piece until the rivet head sits flush against the nozzle. The mandrel will be gripped by the internal jaws.
4. Position on workpiece. Slide the rivet body into the drilled hole. Hold the riveter perpendicular to the workpiece — angled tools deform the head.
5. Pull. Squeeze handles fully. Repeat 2–4 times until the mandrel breaks with a sharp "pop". The mandrel break is the audible signal that the rivet has fully set.
6. Eject mandrel. Tilt the tool back so the spent mandrel falls out (or into the collector cup on cordless models). Drop it in the bin, not on the floor — they're sharp.

How to use a rivnut tool — 5-step procedure

1. Drill the panel hole to the rivnut's specified hole diameter (check rivnut packaging — typically rivnut diameter + 0.1–0.2mm).
2. Thread the rivnut onto the tool mandrel. Spin the mandrel by hand until the rivnut bottoms against the tool nose. Don't over-tighten — a half-turn beyond contact is plenty.
3. Insert into panel. Push the rivnut body fully through the panel hole so its flange seats flush against the front face.
4. Pull. Squeeze handles (plier-style) or operate the lever (lever-style). The rivnut body collapses against the back of the panel, locking it into the hole. Stop when the resistance peaks — over-pulling strips the panel grip and the rivnut spins.
5. Unscrew tool. Spin the tool handle/mandrel anti-clockwise to free the tool from the rivnut. The rivnut stays in the panel, threaded ready for an M-thread machine screw.

Common problems and fixes

Brand reality — AIMS-stocked vs forum-recommended

Production volume — when to upgrade tool tier

The right tool depends on rivets-per-session more than rivets-per-year.

• Under 20 rivets/session, occasional: Short-arm hand riveter. Trax or TTL entry. The tool spends most of its life in a drawer.
• 20–100 rivets/session, regular: Quality short-arm or long-arm. Champion CBRG-1 or Marson TT55D class. Hand fatigue starts mattering above 50/session.
• 100–500 rivets/session, daily: Pneumatic (if compressor on-site) or cordless (mobile/site). DeWalt 20V XR, Milwaukee M18 FUEL, Makita 18V class. Hand-tool fatigue becomes injury risk.
• 500+ rivets/session, production: Pneumatic on a balancer + bench feeder, or top-tier cordless with multiple batteries. Production sheet metal, factory assembly, trailer build.

Forum quote that captures it (r/Tools, "Need an extremely robust rivet tool"): "I need to install 6000 aluminum rivet nuts per day. The current tools I'm using only last a few months." Production at that scale wears out workshop-tier tools fast — and pneumatic on a balancer or production-spec hydraulic is the only durable answer.

Pop rivet vs screw — is a rivet stronger?

The most-Googled rivet-gun-cluster question. The honest answer: depends on direction.

In shear (loads parallel to the panel surface — the dominant mode in most sheet metal joints), a quality 4.8mm steel pop rivet has comparable shear strength to a similar-diameter sheet metal screw. Both fail at the cross-section of the fastener body.

In tension (loads pulling the rivet head away from the panel — pull-out direction), a screw with deep thread engagement and material backing wins. A pop rivet relies on the mandrel-formed back-side bulge, which is smaller than a deep-threaded screw's grip surface.

In vibration, the rivet wins decisively. A screw can back out under vibration cycling; a rivet cannot — there's nothing to back out. This is why ducting, aircraft skin and trailer panel work use rivets despite the screw's tension advantage.

For removability, the screw wins. A rivet is permanent — removal means drilling the head off. A rivnut is the hybrid: rivet-set permanent in the panel, but it accepts a screw that's removable.

Frequently Asked Questions

What is a rivet gun used for?

A rivet gun sets a rivet — pulling the mandrel of a blind/pop rivet to expand it behind a workpiece, or collapsing a rivnut into a panel. The advantage over screws: no back-side access needed. Typical AU trade jobs include sheet metal fabrication, automotive panel repair, trailer body building, marine alloy hulls, signs, ducting, white-goods assembly, and HVAC lap joints.

What are the three types of rivet guns?

Broadly five, not three: (1) hand short-arm — the workshop entry tool; (2) lever / long-arm — for larger or harder rivets; (3) pneumatic — air-powered production-tier; (4) cordless — battery-powered with mandrel collector, mobile/site work; (5) rivnut tool — specifically for threaded rivet inserts. Plus the specialty aviation rivet gun for solid rivets (pneumatic hammer style — completely different product class).

What's the difference between a pop rivet gun and a rivet nut tool?

A pop rivet gun sets blind rivets — solid mandrel pulled through a hollow rivet body that expands behind the panel. A rivet nut tool installs rivnuts (threaded blind inserts) — the tool screws onto the rivnut, pulls to collapse the body, then unscrews leaving an M-thread in the panel for a screw. Different heads, different mandrels, different stroke geometry. Some multi-function tools (Trax ARX-HF207) do both with adaptor swap.

Is a pop rivet stronger than a screw?

Depends on direction. In shear (forces parallel to the panel), comparable. In tension (pulling head away from panel), a screw with deep thread engagement wins. In vibration, the rivet wins decisively — it can't back out. For permanent sheet metal work, rivets dominate; for serviceable joints, screws or rivnuts (which accept screws) are the right call.

How do I clear a jammed mandrel?

Tilt the tool back sharply so gravity drops the stem out the rear. If stuck, use a thin pick, paper clip or stem-extractor wire to push it from the front. For cordless tools, empty the collector cup. Premium hand riveters and quality cordless tools clear mandrels reliably; cheap tools jam every dozen rivets and are the #1 forum complaint.

Do you need a special tool to install rivet nuts?

Yes — a dedicated rivnut tool (also called a nut rivet gun or nutsert tool). A standard pop rivet gun won't work because the mandrel geometry is different. However, a workshop hack exists: pop rivet tools can install small rivnuts (M3–M6) with custom DIY mandrels, documented across r/Machinists threads. For anything beyond occasional small sizes, a dedicated rivnut tool is the right answer.

Are rivnut tools worth buying?

For any workshop doing more than 20 rivnuts a year — yes. The alternative is welding nuts to thin panels (requires access to both sides, distorts thin material) or tapping threads into thin sheet (rarely deep enough for reliable thread engagement). A plier-style rivnut kit handles M3–M6 occasional work; lever or ratchet tools for M3–M10 regular work; pneumatic or cordless for production. AIMS Trax ARX-HRN2K and Champion H2033-2 cover the workshop range.

Why does my rivnut spin when I try to unscrew it?

The rivnut has been over-set — the body collapsed past maximum, stripping the panel-back grip, so the rivnut now rotates freely in the hole. Once it spins, it can't grip a screw and can't be removed by unscrewing. Fix: drill the rivnut head off with an HSS bit slightly larger than the rivnut body, push the remains through, install a new rivnut and stop pulling at the resistance peak next time. Ratchet-action rivnut tools with stroke limiters prevent this in production.

Can rivnuts be removed?

Yes, but not by unscrewing — that's the screw's job, not the rivnut's. To remove: drill the rivnut head off with an HSS drill bit one size larger than the rivnut hole diameter, push the collapsed body through with a punch, drill out any remaining material. Replace with a new rivnut. Some specialty tools exist for non-destructive removal but are rare in AU workshops.

Can I use a drill as a rivet gun?

Yes, with a drill-attachment rivet adaptor (Kincrome Ezi-Riv, similar) — but every forum review flags the speed issue. r/Tools direct: "Those drill ones are painfully slow. It'll take 10+ seconds to pull a rivet and reset the tool." Workable for occasional rivnut installation in a workshop already equipped with quality cordless drills; not the right tool for any volume of blind rivet work. A dedicated cordless rivet gun beats a drill attachment by 5–10× speed.

Pneumatic vs cordless rivet gun — which is better?

Depends on workshop setup. Pneumatic is the production-tier standard if you have shop air — fast (sub-2 seconds per rivet), light (no battery weight), simple, with low CFM demand (1.5–4 CFM at 90 psi). Cordless is the mobile/site-work answer — no air line, no compressor, modern brushless cordless rivet guns (DeWalt DCF403, Milwaukee M18 FUEL) match pneumatic speed but cost more upfront and need battery management. Workshops doing fixed-bench production lean pneumatic; mobile trade and fleet/site work lean cordless.

What's the best rivet gun brand?

Brand depends on tool tier. Hand: Marson TT55D is the AU pro standard pop riveter (forum-quoted across r/Tools). For AIMS supply, Champion CBRG-1 and CBRG-2. Pneumatic: Chicago Pneumatic is the global aerospace standard. Cordless: r/Tools consensus favours DeWalt 20V XR over Milwaukee M12 (slow) and Milwaukee M18 FUEL or Makita 18V are the production picks. Rivnut production: Astro Pneumatic ADN38 (US), Metabo NMP 18 LTX BL M10 (German cordless top-tier).

Do I need an aviation rivet gun for sheet metal work?

No. Aviation rivet guns are pneumatic hammer-style tools that drive solid rivets for aircraft skin — a completely different product class. AU sheet metal trade uses blind/pop rivets (and rivnuts), set by blind rivet guns (hand, lever, pneumatic, cordless). Aviation 3x/4x rivet guns require a bucking bar held on the back side and the trigger-feathering skill that aircraft sheet-metal workers spend years learning. If you're not maintaining aircraft, you don't need one.

How long does a rivet gun last?

Premium hand riveters (Champion, Marson, Chicago Pneumatic): tens of thousands of rivets — most last decades in trade use. Quality cordless: 5+ years of daily trade use, motor and pull-mechanism are serviceable. Cheap unbranded riveters (eBay/Temu): jaws round off in 100–200 rivets, mandrels jam constantly — a false economy. The forum reality from r/Tools: pay the premium up front, get a tool that outlasts the apprentice who wears it.

What rivet size does my rivet gun take?

Most hand riveters ship with 3–4 interchangeable nose pieces covering 3.2mm (1/8"), 4.0mm (5/32"), 4.8mm (3/16") and sometimes 6.4mm (1/4"). Check the tool spec for max rivet diameter — short-arm hand riveters typically top out at 4.8mm in aluminium and 4.0mm in steel. Larger rivets need long-arm, lazy-tong, pneumatic or cordless tools. Always match the nose-piece nozzle to the rivet diameter exactly — wrong size deforms the rivet head and causes mandrel slip.
