Specification:
DIN6797A Stainless Steel External Teeth Lock Washers are manufactured according to the DIN6797A standard and are designed with external serrations that provide enhanced locking performance in bolted connections. The teeth on the outer edge create a strong gripping effect between the washer and the mating surface, helping prevent fastener loosening caused by vibration, shock, or repeated loading. These washers are commonly produced from high-quality stainless steel materials such as SUS304 and SUS316, offering excellent corrosion resistance, strength, and durability for various industrial environments.
