The nylon material prevents loosening from vibration and cross threads to stop the nut from backing off of the fastener. The insert deforms elastically over the threads of the screw, but threads are not cut into the nylon. The nylon insert locks the nut in two ways. First, it forces the bottom face of the screw threads against the top face of the nut threads, increasing the friction between the two. Second, the nylon applies a compressive force against the screw itself. ProductSiteLaunchDate : 2013-10-24T00:00:01-07:00 Size : Onesize Style : Nylon Lock Nut UnspscCode : 31161700
