Product Features


Internal tooth lock washer is a type of washer used to prevent bolts and nuts from loosening due to vibration or other types of movement. It is called an internal tooth lock washer because it has teeth or ridges on the inside surface of the washer that bite into the surface of the bolt or nut and prevent it from turning.


Internal tooth lock washer is typically made of steel and is available in a range of sizes to fit different bolts and nuts. It is installed between the bolt head or nut and the surface it is fastening to. The teeth on the washer should face toward the surface being fastened.


Made of 304 stainless steel, excellent corrosion resistance and can be used in humid environments.

The lock washer generates a spring force between the holder head and the bottom plate to maintain the hardness of the washer and prevent the bottom bolt bolt bolt or base plate bolt thread from hardening, causing more friction and resistance to rotation.
