Spherical Washer Buying Guide

Choose spherical washer hardware by first identifying whether the application requires a matched set for a spherical collar nut or an individual seat or dished washer for clamping on a non-parallel surface. Then compare the stated size, material, dimensions, finish, and whether a complete set or individual component is needed.

Use Cases

Support matched fastening assemblies

Spherical washer sets provide matched components for fastening assemblies that use spherical collar nuts. Available set options include carbon steel and stainless steel constructions.

How to Choose

Match the component and size

Select a washer set, spherical washer seat, or dished spherical washer based on the assembly configuration. Confirm the stated size, such as M6, M12, M16, M24, M30, or M48, along with listed inside diameter, outside diameter, and thickness where provided.

Applications

Clamp on non-parallel surfaces

Individual spherical washer seats and dished spherical washers are intended for clamping components where contact surfaces are not parallel. Their spherical or dished form helps accommodate angled contact or surface misalignment during clamping.

Additional Information

Compare materials, finishes, and ordering format

Product summaries include steel, carbon steel, and stainless steel options. Some carbon steel sets have a black oxide finish, while certain seats are matte silver. Many seats and washers are sold individually, and some sets offer separate top and bottom sections upon request.

Planning Guide

Plan the right fit before choosing

Start with the assembly type

Decide between a set and an individual clamping component

Matched spherical washer sets are designed for fastening arrangements requiring this washer style, including assemblies with spherical collar nuts. Individual spherical washer seats and dished washers are suited to clamping configurations on non-parallel surfaces.

  • Choose a matched set for specified spherical collar nut assemblies.
  • Choose a washer seat for clamping on non-parallel surfaces.
  • Choose a dished spherical washer where angled contact must be accommodated during clamping.
  • Consider individually sold components when the required quantity does not call for a set.
Confirm fit details

Use stated sizes and dimensions to narrow the options

The available summaries identify hardware across several sizes, including M6, M12, M16, M24, M30, and M48, plus inch-designated washer sets. Some products also list inside diameter, outside diameter, or thickness for more specific comparison.

  • Match metric size designations to the stated application requirement.
  • Check outside diameter when it is specified for a washer set.
  • Compare listed thickness and inside diameter for individual washers and seats.
  • For the M48 seat, confirm the stated 2 in. male I.D. requirement.
Compare material and configuration

Select the stated construction and component arrangement

Steel and carbon steel options are represented for clamping and fastening assemblies, while stainless steel options are available in sets and washer seats. Certain sets are precision-machined, and the M24 leveling washer set uses paired washers with a matched concave curve.

  • Select steel or carbon steel where those constructions are specified.
  • Select stainless steel when the assembly calls for a stainless steel washer option.
  • Consider black oxide sets when that finish is part of the hardware requirement.
  • For M24 fastened connections, compare the paired stainless steel leveling washer set.
