1-3/8-6 GR 8 NYLON INSERT LOCK NUT YELLOW ZINC

A Grade 8 Nylon Insert Locknut, sometimes referred to as a stop nut, is a heat treated hex nut with a nylon-filled collar at its back end. When the bolt reaches the collar, the threads and nylon form a tight, frictional fit, restricting movement of the bolt when it is subjected to vibration. Designed to be used in structural applications with a Grade 8 bolt.
