External tooth washers are fasteners specially used to enhance the locking and anti-loosening effect of bolts and nuts. They are characterized by having multiple external teeth that can tightly bite on the surface of the bolt head or nut to prevent loosening. The standard number of external tooth washers is GB862.1. A notable feature of the external tooth washer is its solid structure, which can withstand the impact, collision, smashing, pressure and other external forces of coal, gangue or other materials. This kind of gasket can also adapt to the uneven and bending needs of the coal mining face floor.
