NFE 25-511 is a contact (locking) washer that prevents loosening of threaded connections by forming a reliable bond between the surfaces of the bolt or nut head and the base material. It is used in the assembly of metal structures. It has 4 types of configuration: L, M, N and toothed.

Stainless steel grade A2 allows the fasteners to be used at high temperature extremes and in aggressive wet environments.
