Speed Nut® are spring steel fasteners that replace threaded nuts, lock washers and spanner washers. They are one-piece, heat-treated and self-locking. Useful for many industries and applications, Speed Nut® can be found in smaller components and inside electrical or mechanical components where space is a premium. The Flat Type Speed Nut® has led the way to newer, self-retaining versions.
