Spherical Washer Sets
, also known as Self-Aligning Washers
or Equalizing Washers
, are a great solution for fastening applications on an uneven surface. The washer set consists of a “top” half that is convex and a “bottom” half that is concave. The top washer has a slightly narrower ID than the bottom washer while both have the same radius. This enables a bolt or screw to pass through both washers and “self-align” allowing for a flat clamping washer surface. The spherical washer sets are designed for a 3-4 degree angle of correction. Morton Machine Works manufactures the sets in case-hardened carbon steel with a black-oxide finish or in 303 stainless steel. Variations in material or surface coatings are available upon request. Morton offers spherical washer sets from stock in bolt sizes
of 3/32″ to 2-3/4″
available for same day shipping.
