DIN985 Nylon Self-Locking Nut Anti-Slip hex coupling nuts

Short Description:

Self locking nuts generally rely on friction, and their principle is to press the embossed teeth into the preset holes of the sheet metal. Generally, the aperture of the preset holes is slightly smaller than that of the riveted nuts. Connect the nut to the locking mechanism. When tightening the nut, the locking mechanism locks the ruler body and the ruler frame cannot move freely, achieving the purpose of locking; When loosening the nut, the locking mechanism disengages the ruler body and the ruler frame moves along the ruler body.

Description

Correct Working Principle ：
- The DIN985 Nylon Insert Lock Nut creates a "prevailing torque" through the elastic deformation of the nylon ring. When the bolt thread enters the nylon collar, it creates a high-friction connection that resists loosening under extreme vibration and shock.
