Value Collection FWUI81251-025BX Uss Flat Washer

Product Description

The VALUE COLLECTION FWUI81251-025BX is a USS flat washer designed for use with 1-1/4 inch screws and fasteners. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this washer provides corrosion resistance and load distribution across bolted connections. The large outer diameter spreads clamping force over a wider surface area, making it well suited for applications where bearing surface matters. Plumbers, electricians, HVAC technicians, and general contractors install USS flat washers as part of structural and mechanical assemblies across residential and commercial jobsites.

This washer follows USS (United States Standard) dimensional standards, which call for a larger outer diameter relative to the screw size compared to SAE washers. It is used in general-purpose bolted assemblies, pipe hangers, equipment mounting, and structural connections where a broad bearing surface is required. The zinc yellow dichromate finish suits indoor and moderately corrosive environments. Minimum order quantity is 25 pieces per order.

Installation Notes

Install using hand tools or impact drivers appropriate to the fastener assembly. Ensure mating surfaces are clean and free of debris before seating the washer. Always torque fasteners to the specification required by the equipment or structural application, not the washer alone. This washer is intended for use with compatible Grade 8 or lower-grade hardware as determined by the assembly requirements.
