Nylon Insert Hex Lock Nut - Steel, M6-m48, Metric Thread | Vibration Resistance, Secure Grip, Reusable, Sealing Capability, Grade 4.8-12.9

We export Nylon Insert Hex Lock Nut that have a captive nylon washer mounted in their top to create a prevailing torque type lock nut.
The undersized washer forms a compression grip that binds on the threads of the mating fastener to resist loosening.
Due to limitations of the non-metallic insert, the nuts cannot be used at elevated temperatures or with certain chemicals but the nylon washer does provide a gas and moisture seal.
Various colors of nylon are used.
Regular, thin pattern and machine screw nylon insert lock nuts are used in aerospace, agricultural equipment, appliances, avionics, computers, furniture, home and garden, lighting, medical equipment and vehicles (auto, truck and trailer).
Heavy pattern types are used on bridges and buildings, in heavy industry, and on oil field machinery and railroad equipment.
Nylon insert lock nuts are also known as: aircraft lock nuts, elastic lock nuts, elastic stop nuts, nyloc nuts, nylock nuts, nylon insert stop nuts, stop nuts.
Because the washer largely returns to its original form, nylon insert lock nuts may be reused a limited number of times. Lock washers are not used with prevailing torque lock nuts.
