M6-1.00 METRIC NYLON INSERT LOCK NUT DIN 982 CLASS 8 ZINC

Metric nylon inset lock nuts are basically a hex nut with a nylon-filled collar at its back end. When a screw reaches the collar, the threads and nylon form a tight, frictional fit, restricting movement of the screw when it's subject to vibration.
