Internal Shakeproof Washer BZP, Black & A2 Stainless Steel
These shakeproof washers have serrated prongs (or teeth) inside a metal disc. The disc works to hold the screw in place, while the teeth lock into the head of the nut being tightened. The teeth are slightly bent to provide a secure hold and will not budge under the strain of weight or vibrations.
