Value Collection FWUI81371-025BX Uss Flat Washer 1-3/8 in

Product Description

The VALUE COLLECTION FWUI81371-025BX is a USS flat washer designed for use with 1-3/8 inch fasteners in heavy-duty bolted assemblies. Manufactured from Grade 8 alloy steel with a zinc yellow dichromate finish, this washer provides corrosion resistance and high load-bearing capacity. It features a 1.493 inch inside diameter, 2.780 inch outside diameter, and 0.213 inch thickness, conforming to USS flat washer dimensional standards. At 0.19 pounds, it is a solid, substantial washer suited to structural and mechanical applications. Licensed tradespeople, millwrights, pipefitters, and mechanical contractors commonly specify Grade 8 alloy steel hardware where high-strength fastener assemblies are required.

This washer is appropriate for use in structural bolting, industrial equipment assembly, pipeline flange connections, and heavy mechanical installations. Its USS series dimensions provide a wider bearing surface than SAE-standard washers, making it well suited for distributing clamp load across larger clearance holes or softer substrate materials. The zinc yellow dichromate coating meets typical corrosion resistance requirements for indoor and light outdoor industrial environments.

Key Features

• Grade 8 alloy steel construction for high tensile and shear strength applications
• Zinc yellow dichromate finish provides corrosion resistance and surface protection
• USS flat washer series with wide bearing surface for improved load distribution
• 1.493 inch ID fits 1-3/8 inch nominal screw or bolt size
• 2.780 inch OD and 0.213 inch thickness meet standard USS dimensional requirements

Compatibility

Designed as a standard USS flat washer replacement for use with 1-3/8 inch nominal diameter fasteners in industrial, structural, and mechanical bolted connections.

Installation Notes

Installation is performed by qualified tradespeople including pipefitters, millwrights, ironworkers, and mechanical contractors. De-energize or depressurize any system before servicing fastened joints. Ensure mating fastener grade and finish are compatible with the washer material to avoid galvanic corrosion or strength mismatch. Follow applicable structural or mechanical codes, including AISC or ASME standards, when specifying hardware in load-bearing assemblies.
