Speed Nuts

A speed nut is a spring-steel fastener that pushes or threads onto a screw or stud to give a fast, captive, vibration-resistant grip — no standard nut and wrench required. Often called Tinnerman or quick nuts, they are used to attach trim, emblems, panels, covers, and brackets in automotive, appliance, HVAC, and sheet-metal work. Eugene Fastener & Supply stocks speed nuts in common screw sizes.

The spring-steel arms flex over the screw threads and bite back to resist back-off, making installation quick and tool-light for high-volume assembly. We sell by the piece or in bulk and ship same day on orders placed before 2pm Pacific.

Where Speed Nuts Are Used

Speed nuts shine in high-volume, light-duty assembly where speed matters more than maximum clamp load: automotive trim and emblems, appliance and electronics panels, HVAC covers, signage, and sheet-metal brackets. They install with a push or a few turns and resist loosening from vibration. For heavier or load-rated joints, use a standard hex or lock nut instead.

FAQ

What is a speed nut?

A speed nut is a spring-steel push-on or threaded fastener (often called a Tinnerman or quick nut) that grips a screw or stud for fast, captive, vibration-resistant attachment without a standard nut and wrench. It is used for trim, panels, and covers.

What is a Tinnerman nut?

Tinnerman is a well-known brand of speed nut, and the name is used generically for spring-steel sheet-metal nuts. We stock equivalent speed/quick nuts in common sizes.

How do you install a speed nut?

Push it onto a stud or thread it onto a screw; the spring-steel arms flex over the threads and bite back to hold. Many install by hand or with a screwdriver, which is why they are favored for high-volume assembly.

Are speed nuts strong?

They are light-to-medium duty, built for fast captive retention and vibration resistance rather than high clamp load. For load-rated joints use a standard hex or lock nut.
