M3 Carbon Steel Nylon Insert Lock Nut DIN985

Metric DIN 985 nylon insert lock nuts are prevailing torque type lock nuts which have a permanent undersized non metallic insert (nylon/polyamide) that produces friction between threads of mated components thereby increasing the resistance to loosening forces.

Nylon insert lock nuts may be re-used a limited number of times because the threads of the mating bolt deform but do not cut into the polymer insert.
