Stainless Steel Washer M8, 25 Pieces Large Flat Washers Stainless Steel A2 V2A Black Sealing Ring O-ring for Screws and Threaded Bolts

A2 V2A Stainless Steel: The washers are made of 304 stainless steel, burr-free and resistant to deformation. These stainless steel washers are corrosion and rust resistant and can be used outdoors or in humid environments. Size: We offer 25 M8 stainless steel washers with an 8.4 mm inner diameter, 16 mm outer diameter, and 1.5 mm thickness. Prevents Loosening: When the screw is tightened, the locking washer is compressed, increasing friction and making the screw less likely to loosen. Therefore, they can be used in machinery and equipment frequently subjected to vibration or shock. Enhanced Sealing: The O-ring fills the gap between the screw and the workpiece to ensure a better seal and prevent leaks of liquids or gases. They can therefore be used in hydraulic systems or pipe fittings. Reduces wear: In machines and equipment with a large number of threaded connections, locking washers disperse the pressure generated by the screws or bolts on the parts, thus reducing wear and extending their service life.
