Washers
Spherical Washers
A spherical washer set has a convex and a concave washer that seat together, letting the bolt head and nut align at an angle to the joint surface. The pair compensates for angular misalignment and uneven clamping faces.
Used under bolt heads and nuts on jigs, fixtures, presses and machinery with angled or uneven seats. Bought by toolmakers and machine builders.
