Spherical Washer Sets, also known as equalizing washers, are a great solution for assuring even clamping pressure on critical fastening applications.
 The top half of the washer set has a convex shape and a smaller ID. It mates with the bottom half that has a concave surface and a larger ID.Â
This allows for a 3 to 4 degree angle adjustment for the bolt or fastening device.Â
The washer sets are precision machined from 303 stainless steel and case-hardened carbon steel. Size range begins at 1/4″ ID up through 2-1/2″ ID.Â
