Products widely used in electrical appliances, elevators, towers, medical machinery supporting above, etc., a disc-shaped improved products, quality in line with the NFE-S standard, The working principle is to use the product in the force generated by the rebound tension to play the role of anti-loosening and anti-slip. The French lock washer is an upgraded version of the disc washer, the improved design of the washer will greatly enhance the anti-loosening effect. The installation of the gasket to the pressure level can ensure that the tightened parts on the stress distribution are uniform. Due to the strip marks on the gasket, it prevents the threads of the screw or nut from loosening. Due to their elasticity, they compensate for the sinking of the assembled material and minimize pressure loss, making them a disc improvement. The quality of French lock washers conforms to DIN 6796. The working principle is to use the tension generated by the rebound of the product after the force is applied to play the role of anti-loosening and anti-slip.
