Screws that have undergone anti-loosening treatment are called anti-loosening screws, which are most suitable for the fastening of moving parts. They were first used in American aerospace aircraft and later promoted to the American automobile manufacturing industry. As manufacturing technology matures and costs decrease, It is widely used in multiple industries.
Anti-loosening of double nuts is also called anti-loosening of counter nuts. When two counter nuts are tightened, there is always interaction pressure between the two counter nuts. This pressure will be transmitted to the contact surface of the screw thread. The tighter the counter nuts are screwed, the greater the pressure between the contact surfaces of the screw threads, the greater the contact pressure, the greater the friction resistance distance, and any one of the two nuts needs to overcome the screw thread to rotate. Friction between.
