Non-Metallic Insert Nylon Lock Nuts

The non-metallic insert nylon lock nut is an upgraded version of the ordinary hexagonal nut. It has an extra non-metallic insert, and nylon is generally used as the medium. After the cold heading and tapping process is completed, a pressing process will be added, that is, a section of nylon ring without internal thread is pressed into the top of the metal nut to make it a whole. Due to the addition of the nylon ring, when the bolt is screwed into contact with the nylon ring, the resistance generated eliminates the gap on the side of the thread, causing a certain frictional resistance on the side of the thread, so that the anti-rotation force of the nut also increases accordingly, plus the nylon material. The characteristics of fatigue resistance and vibration absorption can effectively control the swing of the bolts and make the bolts not easy to loosen.
