Description
Internal tooth lock washers have teeth on the inner dimension of the washer and the outside of the washer is smooth. They are made for fasteners who have a smaller head. When the head is fastened into the hole, the internal teeth will help grab the surface.
Features:
- Vibration resistant joint
- The twisted shape also creates constant flex, actually driving the washer further into the joint material during vibration
- Provides greater resistance to loosening and creates a stronger, more dependable joint
- Resisting against the force of the washer being compressed
