DIN74361CFastening Devices For Bolt Centering - Form C - Spring Lock Washers for automotive

M12M14M18M20M22DIN74361-C Tire Spherical Spring Washers Tapered Open Spherical Spring Washers, Automobile Tire Spherical Spring Washers, Spherical Elastic Washers DIN74361 Washers. The basic function of spring washers is to give force to the nut after it is tightened, increasing the friction between the nut and the bolt! That is, in order to prevent the vibration of the equipment in operation caused by the loosening of the fastening bolt and increase a protective measure.
65MN material, hardness 44-50HRC.
Surface treatment: blackening, phosphating, galvanizing.    

The anti-loosening principle of the spherical spring washer is that after flattening the spherical spring washer, the spherical spring washer produces a continuous elastic force, so that the threaded connecting pair of the nut and the bolt continuously maintains a friction force and produces a resisting torque, thus preventing the nut from loosening. At the same time, the sharp corners of the openings of the spherical spring washers are embedded in the surfaces of the bolt and the connected part respectively, thus preventing the bolt from rotating relative to the connected part.
From the role of the spherical spring washer and the principle of view, the spherical spring washer loosening is not a good method of preventing loosening or should look for more ideal by increasing the friction resistance moment of the prevention of loosening method.
