Toothed External Locking Washer

A toothed external locking washer is a small component used in mechanical connections, whose main function is to prevent loosening by increasing friction between bolts and nuts. This type of washer typically has a serrated external design that allows it to bite under the bolt head or nut, providing additional anti loosening effect. These washers are usually made of hardened materials to ensure their stability and durability during use. They are suitable for various materials, including plastic, aluminum, and metal, and can play an important role in applications that require high vibration resistance. For example, in some practical operations, when the contact surface is soft, the toothed external locking washer can generate a reaction force through the serrated part, effectively resisting compression force and preventing bolt loosening.
In summary, toothed external locking washers are an important mechanical component widely used in various industrial fields, especially in situations where anti loosening and improved connection reliability are required.
