DIN6798J Internal Tooth Lock Washer Serrated Lock Washer

Internal Serrated Lock Washers 

Internal serrated lock washers are a type of washer with serrations on the inner diameter that grip the surface of the bolt or screw to prevent it from loosening. These washers are commonly used in applications where vibration or movement may cause fasteners to become loose. The serrations provide extra friction and help to secure the fastener in place, ensuring a more secure connection. Internal serrated lock washers are typically made from steel or stainless steel and are available in various sizes to accommodate different bolt or screw sizes.
