65 Mn Belleville Spring Lock Washers for Socket Head Screws

Belleville Spring Lock Washers for Socket Head Screws.
These washers have smaller outside diameters than standard spring lock washers to fit neatly under socket head cap screws. Also known as conical washers, these have a slightly cupped shape that gives them spring-like flexibility to grip tighter than split and toothlock washers. They minimize loosening from wear, temperature changes, and vibration. Serrations on the top and bottom provide extra gripping power. Load-rated Belleville disc springs are also available.
Zinc-plated steel washers are corrosion-resistant in wet environments.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.    

Advantages of dish-shaped lock washers
1. Toothed structure, high amplitude seismic. High preload, not easy to lose.
2. Tooth shape design, uniform load distribution, prevent bending torque loss and bolt deformation.
3. Special tooth pattern planning. Friction and damage to the contact surface can be eliminated when locked.
4. Closed ring planning and pre-tightening will not burst.
5. The development and planning of washers to cooperate with the use principle of bolt loosening, tightening torque, locking structure, and device environment.Mainly used in the automobile industry, railway bridge, construction engineering, agricultural machinery, machinery industry, machine tool equipment, mold, equipment, reducer, gearbox, and a series of products.
