A speed nut, aka sheet metal nut or Tinnerman nut, is a type of
The speed nut was invented in 1923 and patented in 1924 https://patents.google.com/patent/US1512653A/en?assignee=albert+tinnerman&oq=albert+tinnerman&sort=old by Albert H. Tinnerman, son of George Tinnerman, who founded Tinnerman Steel Range Company. The company, established in 1870, originally manufactured sheet metal kitchen ranges. However, after Tinnerman invented the nut to resolve issues with stove shipping, the invention became so successful it led the company away from building stoves to building fasteners.
Tinnerman Products was formed in 1939, and evolved from the Speed Nut development with manufacturing plants in Cleveland, Ohio. A manufacturing plant was constructed on Brookpark Road in the early 1950s. Tinnerman Products later merged with Eaton Yale & Towne in 1969. In 1999, Eaton sold Tinnerman to TransTechnology for $173 million. In 2009, ARaymond purchased Tinnerman for an undisclosed sum.

. As the fastener is tightened in the nut the prongs are drawn inward until they exert pressure on the root of the thread on the fastener. When the fastener is tightened, the base of the nut, which is arched, elastically deforms and applies a force to the fastener, which locks it from loosening under vibrations.
There are many different types of speed nuts, mostly dependent on the shape of the nut, how it attaches to the workpiece, and what type of screw can be used. Most types are designed for either machine screw
A screw and a bolt (see '' Differentiation between bolt and screw'' below) are similar types of fastener typically made of metal and characterized by a helical ridge, called a ''male thread'' (external thread). Screws and bolts are used to f ...

A flange nut is a nut that has a wide flange at one end that acts as an integrated washer. This serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen ...
