What is a speed nut?
A speed nut is a U-shaped or flat pressed-steel clip with internal teeth or arms that grip a smooth screw or stud shank as it's pushed through. The teeth flex outward while the screw passes, then spring back to hold it — so you get fast, tool-free retention without cutting a thread or tapping a hole. It's the same mechanism whether the nut is a U-type clip that hooks over a panel edge or a flat disc that pushes straight onto a shaft.
Speed nut types AIMS stocks
- U-type speed nuts — clip over a panel edge with spring arms gripping the screw shank from one side. Supplied as an assortment refill covering a range of panel-clip dimensions.
- Flat / push-on speed nuts — disc-shaped, with internal teeth that grip a smooth shaft pushed straight through. Available as a dedicated flat assortment refill and as part of the mixed CA380 kit.
- Assortment kits — the Champion CA380 (390 pieces, mixed U-type and flat sizes) and the GJ Works GKA182 (180 pieces) give a workshop or service vehicle a spread of common sizes in one kit rather than buying single packs.
- Single-size packs — for example the Champion NNU8899, a 13.65 x 11.8 x 5mm zinc-plated speed nut supplied 100 to a pack, for jobs that go through one size in volume.
Where speed nuts are used
Speed nuts earn their place wherever fast, tool-free screw retention matters more than high load capacity — automotive trim and panel fixing, appliance and cabinet assembly, sheet metal fabrication, and general repair work where running a screw into an untapped panel saves a tapping or threading step. They're a mainstay in automotive trade and panel-beating work in particular, where OEM trim and badge fixings are commonly speed-nut retained.
Where not to use speed nuts
Speed nuts are light-duty fasteners. Don't use them for structural or load-bearing joints, safety-critical fastenings, or any assembly that needs to be removed and refitted repeatedly — the spring teeth deform on removal and lose retention force. For those applications, use a standard threaded nut and bolt, or a captive/clip nut designed to be serviceable.
Material and finish
AIMS's speed nut range is zinc-plated steel, giving a durable everyday finish for indoor and general workshop use. If you need a different material or finish for a corrosive or specialised environment, get in touch and we'll help you find the right option.

Frequently Asked Questions
What is a speed nut?
A speed nut (also called a push-on nut or U-clip nut) is a pressed spring-steel fastener that grips a smooth screw or stud shank through spring tension, without needing a tapped hole or thread. Pushing the screw through deflects the internal teeth or arms outward; they spring back to hold the screw under light pull-out load.
How does a speed nut work?
The internal teeth or arms of the speed nut flex outward as the screw shank is pushed through, then spring back to grip it. There's no thread engagement — the retention comes purely from the spring tension of the pressed-steel clip against the screw.
How do you fit a speed nut?
For a U-type speed nut, clip it over the panel edge so the arms line up with the screw hole, then drive the screw straight through — the teeth grip as it passes. For a flat/push-on speed nut, push it directly onto the smooth shaft or shank until it seats.
How do you remove a speed nut?
Prise the clip off with a flat-blade screwdriver or panel tool, working around the edge to release the gripping teeth from the screw shank. Because removal deforms the teeth, a speed nut generally shouldn't be reused once taken off — fit a new one.
What's the difference between a U-type and a flat (push-on) speed nut?
A U-type speed nut clips over a panel edge, with its spring arms gripping the screw from one side — it's designed to sit on an edge or lip. A flat (push-on) speed nut is a disc that pushes straight onto a smooth shaft or stud, with no panel edge involved. Which one you need depends on whether you're fixing through a panel edge or onto an open shaft.
Are speed nuts reusable?
Not usually. Removing the screw deforms the spring teeth or arms and reduces their grip, so a speed nut is generally treated as single-use. If you need a fixing you'll remove and refit regularly, use a captive nut or a standard nut-and-bolt joint instead.
What material and pack sizes does AIMS stock speed nuts in?
AIMS's speed nut range is zinc-plated steel. It's available as single packs (for example 100 per pack for a specific size) and as multi-piece assortment kits — the Champion CA380 (390 pieces, mixed U-type and flat sizes) and the GJ Works GKA182 (180 pieces) — for workshops that need a spread of sizes on hand.
Speed nut or captive nut — which do I need?
Use a speed nut for fast, effectively single-use fixing of trim, panels or covers. Use a captive nut where the joint needs to be serviceable — removed and refitted more than once, such as an access panel or removable cover. If in doubt, ask our team and we'll help you pick the right fastener for the job.
