What are the main categories of corrugated washers?

Washers (waveform spring washers, serrated washers, stop washers, saddle washers, grounding washers, etc.)

Washers are divided into: flat washer - C grade, large washer - A and C grade, extra large washer - C grade, small washer - A grade, flat washer - A grade, flat washer - chamfer type - A grade, high-strength washer for steel structure, spherical washer, conical washer, square bevel washer for I-beam, square bevel washer for channel steel, standard type tension spring washer, light tension spring washer, heavy tension spring washer, internal serrated lock washer, internal serrated lock washer, external serrated lock washer, external serrated lock washer Single ear stop washer, double ear stop washer, outer tongue stop washer, and stop washer for round nuts.

Plain washers are commonly used in connectors where one is soft and the other is hard and brittle. Their main function is to increase the touch area, dissipate pressure, and avoid crushing the soft material. The fundamental function of the tension spring washer is to apply force to the nut after tightening it, increasing the friction force between the nut and the bolt! The data is 65Mn (tension spring steel), with a heat treatment hardness of HRC44-51HRC, and treated with external oxidation

A spring washer or clamp is an elastic cushion or clamp

Lock washer

A washer that prevents bolts from loosening. The working principle of the lock washer is very simple. It consists of two washers. The outer side has a radial convex surface, while the inner side has a diagonal tooth surface. When installing, the inner inclined tooth surfaces are facing each other, and the outer radial convex surface is in an interlocking state with the contact surfaces of the two ends. When the connecting piece is oscillating and causes the bolt to loosen, it only allows for relative displacement between the inner inclined tooth surfaces of the two washers, causing lifting tension, and then achieving 100% locking.
