DIN6798 external serrated lock washers are an important mechanical part, widely used in various mechanical connections. The outer edge of the washer is designed with a serrated shape, which generates a bite force with the plane of the connected part, thereby providing an additional locking effect. Suitable for threads with specifications of M2-M30.
DIN6798 serrated lock washers can be divided into several types according to the position of the serrations and the shape of the washers, including external serrated washers AZ, internal serrated washers JZ, countersunk V-type and double-sided serrated washers.
GNEE is available in carbon steel and stainless steel A2. Carbon steel is mainly galvanized and boiled black to improve corrosion resistance and aesthetics.
