A4 316 Stainless Steel Internal Tooth Shakeproof Washer, M3, DIN 6798J

RS PRO Plain Stainless Steel Internal Tooth Shakeproof Washer, M3, A4 316This RS PRO internal tooth shakeproof washer can be used to prevent nuts, bolts and screws from vibrating loose in the home or workplace. Shakeproof washers are among the most effective lock washers. Internal tooth washers have serrated prongs (or teeth) on the inside that lock into nuts and bolts when tightened over them. Once these teeth are hooked in, no amount of vibration or weight can budge or loosen the screw. This shakeproof washer is made of stainless steel, which is robust and resistant to corrosion. Because the teeth are on the inside, the final product has a discreet appearance. This washer is designed for use with M3 screws and bolts, and can resist the force of the washer being compressed. Built according to the DIN 6798J manufacturing norm for serrated lock washers, this product has been stringently tested to RS PROs high-quality control standards.Features and Benefits• Shakeproof washer • For M3 screw and bolt size • Internal tooth washer type • Inside diameter of 3.2 mm • Outer diameter of 6 mm • Thickness of 0.4 mm • Made from corrosion-resistant stainless steel (type A4 316) • Plain finish • Conforms with manufacturing norm DIN 6798J for serrated lock washers (Deutsches Institut für Normung, or the German Institute of Standardisation) • RoHS compliant as containing minimal amounts of restricted hazardous substancesRS PRORS PRO is our own brand range and brings you a wide range of high-quality, great value products offering you more choice.
