1. The installation of the anti-loosening washer is very simple, just put the inner helical tooth surfaces of the two washers against each other, and place them between the nut and the connecting material.
2. After the nut is tightened, the radial convex surface on the outer side of the anti-loosening washer is engaged with the contact surfaces at both ends, and the slope angle of the helical tooth surface on the inner side of the washer is greater than the thread angle of the bolt.
3. When the bolt is elongated due to mechanical vibration, the nut will rotate and loosen accordingly. However, the friction force of the outer radial convex surface of the anti-loosening washer is greater than the friction force between the inner helical tooth surfaces, so in this state, only the relative displacement between the inner helical tooth surfaces is allowed to generate lifting tension. The bolt is contracted by elongating the bolt.
4. When the bolt shrinks, the helical tooth surface of the washer will make the nut return to its original position.
5. Lock washers are only suitable for flat and smooth metal surfaces.
6. If the connection material is non-metallic, a metal plate can be fixed on the connection material, so that the lock washer can be used.
7. There is no need to use a torque wrench when installing the lock washer.
8. You can also choose to use pneumatic tools when installing or removing the lock washer.
