Product application

Metric DIN 982 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.

The Nyloc nut is an economic locking nut and ideal in applications where vibration or motion could loosen or undo the nut. The nut can also be used to assist sealing the bolt thread against seepage of oil, water, petrol, paraffin and other liquids.
