SteelToothed Lock Washers—Type J,with Internal Teeth

An external tooth lock washer is a mechanical element used to connect and lock bolts, which has an external gear structure to provide an additional anti-loosening effect in bolted joints. External gear lock washers are washers with special grooves and projections that ensure that the connection remains tight in vibration and shock environments.    

ASME B18.21.1 An internally toothed lock washer is a common fastener used to provide additional tightening force to prevent a bolt or nut from loosening. It has internal teeth that bite into the surface of the bolt or nut during assembly, increasing friction and preventing loosening. ASME B18.21.1 is a standard developed by the American Society of Mechanical Engineers to standardize the dimensional, material, and performance requirements for external toothlock washers. External tooth lock washers are widely used washers in threaded joints. Through its special design and material, it can provide extra tightening force and anti-loosening ability to ensure the reliability and safety of threaded joints.
