Serrated Safety Washers - Light Duty - Type S - Carbon Steel


This unique design of a Disc Spring Serrated Washer means they have a distinct advantage of having serrations on both surfaces that when deflected (tightened on to the mating surfaces), offer a good grip that helps prevent loosening of nuts, bolt and screws.
This product is particularly useful in such applications where vibrations are concerned, such as washing machines, drills etc.
