Metric Steel INTERNAL TOOTH Star Lock Washer

The internal teeth of this washer dig into the head of the screw or bolt as well as the mating surface for a strong, locked connection resistant to vibration.

Internal star washers have a smooth outer surface that will not catch or snag nearby items. The best fasteners to use with these washers have smaller heads such as JIS machine screws, cheese head screws, etc.
