Specification:
Stainless Steel DIN6797J Internal Teeth Lock Washers are manufactured according to the DIN6797J standard and feature a serrated inner tooth design that provides an effective locking effect in bolted connections. The internal teeth grip the underside of the fastener head or nut surface, increasing resistance against rotation and helping prevent loosening caused by vibration, shock, and 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 a wide range of industrial applications.
