The Spring Nut pictured above is the flat-type speed nut. They are a one piece, self-locking, heat-treated, spring-steel fastener that replaces threaded nuts in some applications. When the screw is tightened, the curved spring steel flattens against the surface of one of the mating parts and provides the locking feature. In the tightening process, the spring steel width A expands to a greater width covering a larger area of the mating surface. This has a benefit because of the larger area of coverage but can also mar the surface unless special care is taken. This biting into the surface at the end of the spring is what provides the locking capability. The treads on the screw can also be damaged, i.e., pierced plating, if not properly assembled.
On many applications, they eliminate time consuming assembly operation. Fast and easy to apply. They use both the "turn screw" and "turn nut" method of assembly.
Speed nut fasteners provide maximum holding power at minimum cost per fastener. They never shake loose from vibration, yet can be easily loosened and removed when desired, without worry about rust-frozen screw threads.
These fasteners are normally sold in quantities of 10, 100, 1,000 (or multiples thereof) but discounts are given for full carton orders. You may find that a carton order has the same or more pieces in the carton than an order for 100 or 1,000 and yet has a lower price because we are a volume supplier and reward the customer for volume business.
