M4 Serrated Safety Washers – Light Duty

Product Code: LDS74305

Light Duty Serrated Safety Washers 7mm x 4.3mm x 0.5mm

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.
