Metal washer

Metal gasket (metal washer) to be fitting with a nut on the mat between the parts. For flat shape of the metal ring, commonly used to protect by fitting the surface of the nut scratches, scattered nut on the fitting of a pressure.

Washers are divided into: flat washers-C, large washers-A and C, large washers-C, small washers-A, flat washers-A, flat washers - chamfered-A, Strength washers, spherical washers, tapered washers, I-beam oblique washers, channel inclined bezel, standard spring washers, light spring washers, heavy spring washers, internal gear locking washers, serrated lock washers, Outer gear lock washers, outer serrated lock washers, single ear stop washers, double ear stop washers, outer tongue stop washers, round nuts with stop washers.
Flat washers are generally used in the connector is a soft, one is hard and more brittle, and its main role is to increase the contact area, decentralized pressure, to prevent the texture of the soft crushed. The spring ring of the basic role of the spring is re-nut tightened to the nut after a force to increase the friction between the nut and bolt! Material for the 65Mn (spring steel), heat treatment hardness HRC44 ~ 51HRC, the surface oxidation.
A bead that prevents the bolt from loosening. The working principle of the lock washers is very simple. It consists of two gaskets. The outside is with a radial convex surface, and the inside of the oblique surface. When the assembly, the inner side of the oblique tooth surface between the opposite side of the radial convex surface and the two ends of the contact surface into the state, when the connector by vibration, and the trend of loosening of the bolt, only two pads on the inside of the oblique surface Dislocation, resulting in lifting tension, so as to achieve 100% lock
