Description

Extra Thick Washers are almost 3X as THICK as regular Flat Washers; sometimes used as spacers.

These washers provide a smooth bearing surface against the work surface, protecting it and preventing damage.

These washers are extra large so the load is distributed across a greater surface area. Choose from zinc plated steel or hot-dip galvanised steel.

Flat Washers  

Flat washers are used under bolt heads or nuts to increase the bearing surface area, or to offer protection so that the nut or bolt can be rotated without distortion of the bearing surface.

Flat Washer Types
ASTM F844 USS (United States Standard) Flat Washers

USS flat washers were developed to satisfy engineering requirements in the majority of industrial applications in all fields of manufacturing, maintenance and repair. The Outer Diameter (OD), Inner Diameter (ID) and Thickness (Th) specifications were developed to meet the broadest possible number of applications.

SAE (Society of Automotive Engineers) Flat Washers

SAE flat washers were developed and specified by the Society of Automotive Engineers to meet the requirements of automotive manufacturer applications as broadly as possible. They feature smaller outside diameter when compared with USS washers.
