Steel Thin Pattern Properties

Description A heavy hex nut, 35% less thick than standard heavy hex, with a nylon filled collar at its back end. When a screw or bolt reaches the collar, the threads and nylon form a tight frictional fit, restricting movement between the nut and bolt or screw when subjected to vibration. The nylon insert comes in various colors.
Applications
& Advantages
Thin pattern hex nuts are used when an insufficient number of projecting threads are present to use a full heavy hex nylon insert stop nut.
