Value Collection FWUIS1250-5LBBX Uss Flat Washer

Product Description

The VALUE COLLECTION FWUIS1250-5LBBX is a USS-pattern flat washer designed for use with 1-1/4 inch fasteners in general industrial, mechanical, and structural applications. Made from Grade 2 steel with a zinc-plated finish, this washer distributes load across a wider bearing surface than standard SAE washers, reducing fastener pull-through and surface damage. The zinc coating provides basic corrosion resistance suitable for dry and mildly corrosive environments. With an inside diameter of 1.368 inches, an outside diameter of 3.03 inches, and a thickness of 0.192 inches, this washer meets USS dimensional standards for 1-1/4 inch screw and bolt assemblies. Installation requires no special tooling beyond standard wrenches or impact equipment.

This washer is commonly used in construction, equipment assembly, HVAC equipment mounting, plumbing fixture installation, and general maintenance applications where a larger bearing surface is required. The USS (United States Standard) pattern is the go-to choice when working with coarse or rough-cut surfaces, oversized holes, or where load distribution is a priority over compact fit. It is appropriate for both indoor structural use and sheltered outdoor applications where the zinc finish provides adequate protection.

Installation Notes

Installation is performed by any trade professional using standard hand or power tools. Always place the washer flat against the mating surface with the bolt head or nut seated squarely on the washer face. Inspect mating surfaces for burrs or debris before assembly to ensure proper seating and accurate torque transfer. Follow applicable mechanical or structural codes for fastener torque requirements specific to the assembly.
