Metric Steel INTERNAL SERRATED Star Lock Washer
The aggressive internal serrations of this washer bite into the head of the screw or bolt as well as the mating surface for a strong, locked connection resistant to vibration. Serrated Star Washers provide a stronger hold than Toothed Star Washers because the serrations dig deeper into the connecting fasteners.
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.
