Serrated Countersunk Lock Washers 

A countersunk toothed lock washer with a conical V shape is a type of washer that is designed to provide a secure locking mechanism when used with a screw or bolt. The countersunk design allows the washer to sit flush against the surface of the material, while the toothed edges provide additional grip and prevent the washer from loosening over time. The conical V shape helps to distribute the pressure evenly across the surface of the material, reducing the risk of damage or distortion. This type of washer is commonly used in applications where vibration or movement may cause traditional washers to come loose.
