Truss Head Dome Rivets

Truss Head Dome Rivets for Australian Sheet Metal and Panel Fastening

Truss head dome rivets (also called large flange dome rivets) are blind rivets with an oversized flange head that distributes load across a wider bearing area than standard dome head rivets. The wider flange suits thin sheet, fragile substrates, oversized clearance holes, and applications where pull-through is a concern. For Australian sheet metal fabricators, panel installers, and trade users handling thin or delicate materials, truss head rivets earn their place over standard rivets. AIMS Industrial supplies truss head dome rivets across the standard sizes and materials.

The truss head rivet types we stock

• Aluminium body / steel mandrel — the everyday choice for general sheet metal work
• All-aluminium — for soft or aluminium substrates where galvanic corrosion would be an issue
• Steel body / steel mandrel — stronger joint for heavier substrates
• Stainless steel 304 and 316 — for marine, food-grade, and corrosive environments
• Sealed (closed-end) truss head rivets — for water-tight and dust-tight joints

Where truss head rivets earn their place

• Thin sheet metal fastening — sheet 0.5-1.5mm where standard rivets risk pull-through
• Roof and wall cladding — fastening profiled cladding panels where the rivet head's bearing area matters
• Air conditioning ducting — joining sheet metal sections in HVAC ductwork
• Automotive body panels — fastening interior trim, body panels, and accessories
• Sign and display manufacture — fastening sheet metal and acrylic to backing structures
• Marine fitouts — stainless truss head rivets in saltwater and marine environments

Truss head versus standard dome head

Standard dome head rivets have a head diameter approximately 1.6× the rivet body diameter. Truss head rivets have a head diameter approximately 2.5× the body diameter — significantly wider bearing surface that distributes the clamping load across more material. This matters when:

• The substrate is thin and might tear at the rivet head
• The substrate is soft (aluminium, plastic) and might crush at the rivet head
• The hole is oversized and a standard head wouldn't span the gap
• The application is exposed to dynamic load that would fatigue a smaller bearing area

Sizing — diameter and grip range

Truss head rivets are sized like standard rivets: body diameter (typically 4mm or 5mm for general work) and grip range (the combined material thickness the rivet can fasten). The grip range is given as min-max in millimetres. Choose a rivet whose grip range covers the combined material thickness with a small margin.

Tools you'll need

Truss head rivets require a riveter for installation — the larger flange doesn't require special tooling but the riveter must have adequate force capacity for the rivet diameter. For occasional use, hand riveters work. For daily-use trade work, an air riveter or battery-powered riveter is significantly faster.
