Value Collection FWUIS0560-10LBBX Uss Flat Washer 9/16 in

Product Description

The VALUE COLLECTION FWUIS0560-10LBBX is a USS flat washer designed for use with 9/16 inch fasteners. Manufactured from Grade 2 steel with a zinc-plated finish, it provides a broad bearing surface that distributes load and reduces fastener pull-through. The washer measures 0.62 inches inside diameter, 1.499 inches outside diameter, and 0.132 inches thick. The zinc coating offers baseline corrosion resistance suitable for general-purpose indoor and light outdoor applications. Electricians, plumbers, HVAC technicians, and general contractors use USS flat washers in structural and mechanical assemblies where a larger OD-to-screw-size ratio is required.

This washer follows USS (United States Standard) dimensional standards, which specify a larger outside diameter compared to SAE flat washers of the same screw size. That larger footprint makes it well suited for use with softer base materials, oversized holes, or any joint where spreading the clamping load across a wider area is the priority. It is used across residential and light commercial construction, mechanical equipment mounting, and general maintenance tasks.

Key Features

• USS standard dimensions provide a larger OD-to-screw-size ratio than SAE equivalents
• Grade 2 steel construction for reliable strength in general-purpose fastening
• Zinc-plated finish for baseline corrosion resistance
• 0.62 inches ID fits 9/16 inch screw or bolt shank cleanly
• 1.499 inches OD distributes clamping load over a broad surface area
• 0.132 inches thickness provides consistent bearing surface without excessive stack height

Compatibility

Designed as a standard USS flat washer for use with 9/16 inch screws and bolts in general mechanical and construction assemblies.

Installation Notes

USS flat washers are installed by general tradespeople and maintenance technicians as part of bolted assemblies. Place the washer between the fastener head or nut and the mating surface before tightening. Follow applicable torque specifications for the fastener grade and size being used. Inspect washers for deformation or corrosion before reuse in critical assemblies.
