An external shakeproof washer is a tooth lock washer with sharp teeth formed around the outer diameter.
An external washer works well with round or pan head screws, or generally screws with a larger head.
The external teeth on these shakeproof washers grip to both surfaces whilst tightening, which creates friction in order to stop the nut from coming loose.
External shakeproof washers available in a range of sizes and materials from Fastenright. Specials made to order.
