Value Collection FWUIS2250-5LBBX Uss Flat Washer

Product Description

The VALUE COLLECTION FWUIS2250-5LBBX is a USS flat washer designed for use with 2-1/4 inch screws and bolts. Manufactured from Grade 2 steel with a zinc-plated finish, it provides a broad bearing surface that distributes clamping load and reduces fastener pull-through. The washer meets ASME B18.21.1 dimensional standards, ensuring consistent fit across compliant hardware. With an inside diameter of 2.365 inches, an outside diameter of 4.795 inches, and a thickness of 0.248 inches, this washer suits heavy-duty mechanical and structural fastening applications. Plumbers, electricians, millwrights, ironworkers, and general contractors use USS flat washers regularly in both new construction and retrofit work.

USS flat washers are used in residential and commercial construction, mechanical assemblies, structural steel connections, and equipment mounting. The larger outer diameter of the USS series compared to SAE washers makes it well suited for applications where the fastener hole is oversized, the material is soft, or load distribution over a wider area is needed. This washer is sold individually and is appropriate wherever a 2-1/4 inch nominal screw or bolt is used.

Installation Notes

Install with standard hand tools appropriate to the fastener size. Ensure the washer seats flat against the work surface with the fastener centered in the bore before applying torque. Zinc-plated washers are suitable for dry or mildly humid interior environments; evaluate coating suitability before use in continuously wet or chemically aggressive conditions. No special trade license is required for standard fastener installation, though structural applications may be subject to applicable building codes.
