Product Description
Metric DIN 986 Cap Nut are a combination acorn cap nut and prevailing torque type lock nuts. They 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 . These nuts also have a smooth rounded head that covers the hex nut base. The domed surface protects the bolt threads underneath while providing a finished appearance and may improve safety in certain circumstances.
