Technical Features

  • USS-standard wide body: Larger outside diameter than SAE equivalents, providing a broader bearing surface to distribute fastener load across a greater area and reduce pull-through on softer materials.
  • Zinc finish: Applied coating that offers a baseline level of corrosion resistance for general indoor and moderate-exposure applications.
  • Flat, thin profile: Consistent geometry allows the washer to seat flush under bolt heads or nuts, maintaining even clamping force across the joint.
  • Center hole sized for 1" fasteners: Matches standard 1" threaded bolt and screw shafts for direct compatibility without modification.

Applications

  • General construction and structural assemblies where load spreading under a bolt head or nut is required.
  • Wood, metal, and composite panel fastening where a wider washer body prevents surface damage or pull-through.
  • Maintenance and repair applications calling for USS-specification hardware.
  • Situations where SAE washers are undersized for the joint requirements and a larger outside diameter is needed.
