Value Collection FWUIS112-025BX Uss Flat Washer Steel 25-pack

Product Description

The VALUE COLLECTION FWUIS112-025BX is a USS flat washer designed for use with 1-1/8 inch screws and bolts. Manufactured from steel with a plain finish, this washer provides load distribution across a bearing surface in standard fastener assemblies. The USS (United States Standard) pattern specifies a larger outer diameter relative to screw size, making it well suited for applications where added bearing area reduces pull-through risk or surface damage. Each box contains 25 washers. Inside diameter measures 1-1/4 inches, outside diameter measures 2-3/4 inches, and thickness is 11/64 inches.

These washers are used across a wide range of trade and industrial applications including HVAC equipment mounting, plumbing fixture installation, electrical panel and equipment assembly, structural fastening, and general mechanical assembly. The USS flat pattern is commonly specified when securing softer materials or oversized clearance holes where a standard SAE washer would not provide adequate bearing surface. Sold in a box quantity of 25, this SKU is suited for service technicians and contractors who require a reliable supply of hardware on the job.

Key Features

• USS flat washer pattern provides larger outer diameter for increased load-bearing surface
• 1-1/4 inch inside diameter fits 1-1/8 inch screw or bolt shank with standard clearance
• 2-3/4 inch outside diameter distributes clamp load over a wide area
• 11/64 inch thickness for rigid support under fastener head or nut
• Steel construction for strength in general-purpose fastening applications
• Plain finish — no coating — suitable for use where galvanic compatibility or paint adhesion is a consideration

Compatibility

Designed as a standard USS flat washer for use with 1-1/8 inch fasteners in general mechanical, structural, and equipment-installation applications where the USS large-pattern OD is specified.

Installation Notes

USS flat washers are installed by qualified tradespeople including HVAC technicians, plumbers, and electricians during equipment mounting and structural fastening tasks. Always ensure the inside diameter clears the fastener shank freely and the outside diameter seats fully on the mating surface before torquing. Do not substitute a SAE washer where a USS pattern is specified, as the reduced OD may not meet load distribution requirements. Follow applicable codes and fastener manufacturer torque guidelines for the specific assembly.
