metric square nuts - tetrahedral threaded fastener, flat bottom, top washer plus

Nylock  metric nut - It is a hexagonal nut having a collar at its rear end-filled nylon. Designed for use with machine screws and bolts similar materials. Because it is made of nylon, it is not recommended to use at a temperature of 150-300F.

Metric KEPS- external star nut - this is another pre-assembled surface of the nut is free to rotate with six external teeth of the lock washer.
