Locking toothed flat washer

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.

Function:

Locking and anti-loosening function One of the main functions of the external tooth washer is locking and anti-loosening. Its external tooth design can form additional friction between the bolt head and the nut, thereby increasing the friction and anti-loosening ability of the fastener. This type of washer is usually used in situations where loosening needs to be prevented, such as in shipbuilding, automobile manufacturing, mechanical equipment, medical equipment, chemical machinery and other fields. Improve connection stability The external tooth washer can increase the stability of the connection part through the contact between its external teeth and the bolt head or nut. Its washer structure can play a buffering and isolating role between the two fasteners to ensure the stability and reliability of the fasteners. In addition, the external tooth washer can also maintain a suitable gap between the fasteners when the joint surface is uneven or the surface is worn, preventing direct contact and wear. Preventing liquid and gas intrusion In addition to the above functions, the external tooth washer can also prevent the intrusion of liquids, gases, dust, etc., and play a sealing role. This type of washer can be used in occasions that require sealing, such as automobile radiator gaskets and faucet gaskets.
