STAR WASHER M3 INTERNAL ZPThe Internal Star Washers are positioned between a bolt or screw head and the surface of the material base to be tighten with maximum friction.
Internal Star Washers (also know as tooth lock washers) create a superior locking mechanism with their internal teeth. The teeth work by biting into the head of the fastener in unison with the material that is being fastened. This causes a tight grasp, keeping the screws and bolts in place.
Handy washer to have!
