Steel Hex Flange Nuts, Self Locking Hexagon Nuts

Nylon insert lock nuts are hex nuts 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; some manufacturers use a specific color. 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.
The bolt or axle has one or two holes drilled through its threaded end. The nut is torqued properly and then, if the slot is not aligned with the hole in the fastener, the nut is rotated forward to the nearest slot. The nut is then secured with a split pin, R-clip or safety wire. It is a positive locking device.
Castellated nuts are used in low-torque applications, such as holding a wheel bearing in place.
