Belleville Spring Washer, 3/8" Bolt, 1-3/16" OD, 301 SS

Belleville spring washer, coned disc spring, and conical spring washer are all names for a type of spring that is a conically shaped disc that deflects (flattens) at a given rate. Conical spring washers have a high spring rate, resolve thermal expansion and can produce extremely high loads in a small area. They also absorb shock, provide dampening, and support high tension in bolted applications.
