Lock Washers

Lock washers create tension by “locking” the bolt or screw into the workpiece’s threaded hole. Unlike flat washers, they have serrations on the washer body to prevent rotation and provide a more secure connection than flat washers. These washers are frequently used in high-vibration environments to prevent the loosening of the fastener assembly.
