Value Collection USFW0560050OZ Uss Flat Washer 50 Pack

Product Description

The VALUE COLLECTION USFW0560050OZ is a USS flat washer designed for use with 9/16 inch fasteners. Manufactured from Grade 2 steel with a zinc-plated finish, this washer provides corrosion resistance suitable for general-purpose mechanical and structural assembly applications. It measures 5/8 inch inner diameter by 1-1/2 inch outer diameter and is 7/64 inch thick. The zinc plating adds a layer of protection against oxidation in moderately exposed environments. This item is sold in a minimum order quantity of 50 pieces per package, making it practical for contractors, maintenance crews, and shop stock replenishment.

USS flat washers of this type are used across a broad range of trade applications including HVAC equipment mounting, plumbing fixture installation, electrical panel and junction box assembly, and general structural fastening. The 9/16 inch screw size fits commonly used hex bolts and machine screws in both residential and light commercial construction. The larger bearing surface of the USS pattern distributes load across a wider area compared to SAE-pattern washers, reducing the chance of fastener pull-through in softer substrates or sheet metal flanges.

Installation Notes

USS flat washers are installed by electricians, plumbers, HVAC technicians, and general contractors using standard hand tools or power drivers. Always place the washer over the fastener shank before seating the nut or bolt head against the work surface. Ensure the mating surface is clean and free of debris to achieve proper load distribution. Follow applicable code requirements for fastener specifications when used in structural or code-governed assemblies.
