Value Collection FWUIS100-025BX Uss Flat Washer 1 in

Product Description

The VALUE COLLECTION FWUIS100-025BX is a USS flat washer designed for use with 1-inch screws and fasteners. Manufactured from steel with a plain finish, this washer distributes load across the bearing surface to protect the material being fastened and prevent pull-through. The inside diameter measures 1-1/16 inches, the outside diameter measures 2-1/2 inches, and the thickness is 11/64 inches. Sold in a minimum order quantity of 25 pieces, this washer suits general mechanical assembly, structural fastening, and maintenance applications where a standard USS-series flat washer is specified.

This washer follows USS (United States Standard) dimensional standards, which specify a larger outside diameter relative to the screw size compared to SAE washers. That larger bearing surface makes USS washers well-suited for use in wood, sheet metal, and light structural assemblies where load spreading is the priority. Electricians, HVAC technicians, plumbers, pipefitters, and general tradespeople regularly stock USS flat washers for routine mechanical assembly and equipment installation tasks.

Key Features

• USS series sizing provides a larger OD for improved load distribution over SAE equivalents
• Steel construction for strength in general-purpose mechanical and structural applications
• Plain finish — suitable for interior use or where coating is not required
• Inside diameter of 1-1/16 inches fits 1-inch nominal screw or bolt shank
• Outside diameter of 2-1/2 inches for broad bearing surface coverage
• Thickness of 11/64 inches provides consistent, reliable spacer and load distribution performance

Compatibility

Designed as a standard USS flat washer for use with 1-inch nominal screws and bolts in general mechanical assembly, equipment mounting, and structural fastening applications.

Installation Notes

USS flat washers are installed by general tradespeople and maintenance technicians as part of bolted or screwed assemblies. Always place the washer between the fastener head or nut and the mating surface before tightening. Follow the torque requirements specified by the equipment or structure manufacturer — do not infer torque values from washer size alone. Inspect washers for deformation or corrosion before reuse in critical assemblies.
