Many users will choose the combination screw (SEMS SCREW) to eliminate the action of inserting the washer and greatly reduce the construction time.

The main function of the washer is to provide protection against looseness and protection of the surface of the lock. If the surface of the lock is not flat or the aperture is large, the washer can increase the contact surface to achieve the anti-loose effect.

If the surface of the lock is smooth, the washer protects its surface from screw/nut scratches.
