Nylock Nuts
A nyloc nut, also referred to as nylon insert lock nut (hex nylock nut) is a kind of lock nut. It is a nut with nylon collar insert that resists turning. The plastic/nylon/polymer insert is placed at the top end of the nut, and its inner diameter is slightly smaller than the major diameter of screw. The insert deforms elastically over the threads of the screw, but threads are not cut into the nylon. The nylon insert locks the nut by friction against the screw under the applied radial compressive force. These nuts normally retain their locking ability up to 250°F.
 
These nuts are normally available in White Zinc coating. Other finishes like Yellow/Blue Zinc coating, nickel-plated, bright chromium plated and auto black are also available.
