Spherical Washer Sets, also known as Self-Aligning Washers or Equalizing Washers, are used for fastening applications on uneven surfaces. The washer set consists of a “top” half that is convex and a “bottom” half that is concave.
Spherical Washers Diameters
Spherical Washers are available on the FCH Network with Imperial/US diameters that range from #1 to 5 and with Metric diameters that range from M6 to M48. The length of Spherical Washers is usually measured from the point to the underside of the head.
