Plate nut

A plate nut, also known as a nut plate, is a stamped sheet metal nut that is riveted to a workpiece. They have a long tube that is internally threaded and a plate with two clearance holes for rivets. They were originally developed for the aerospace industry, but are now also common in automotive racing.^[1] These nuts are made up of variety of soft and hard materials.The choice of material depends on environment to which nut is subjected.Soft materials like copper or brass are used when nut is used in electrical application.Hard materials are used when nut is subjected to high stress environment.Sometimes stainless steel or nickel plated nuts are used in order to increase corrosion resistance.

Locknut types are available, which utilize a nylon locking element, much like a nyloc nut.These lock nuts are used when nut is subjected to constant changes in environment or to vibrations.The nylon insert expands and stops vibrations of nut and acts as a locking arrangement. Other types have a floating nut or replaceable locking elements.^[1]
