It is a nut with a nylon collar insert that resists turning. The insert deforms elastically over the threads of the screw, but threads are not cut into the nylon. The nylon insert locks the nut by friction against the screw under the applied radial compressive force. Nyloc nuts retain their locking ability up to 250 °F (121 °C). Authorities disagree on whether nyloc nuts should be reused. 304 stainless steel offers good corrosion resistance in most environments
