Value Collection FWUIS050-100BX Uss Flat Washer 1/2 in Steel

Product Description

The VALUE COLLECTION FWUIS050-100BX is a USS flat washer designed for use with 1/2 inch fasteners in general mechanical, structural, and trade assembly applications. Manufactured from steel with a plain finish, this washer distributes load across a bearing surface to reduce fastener pull-through and protect the mating material. The USS pattern specifies a larger outer diameter than SAE standard, making it well suited for applications where a wider bearing surface is needed. Each box contains 100 washers. The plain finish is uncoated bare steel, appropriate for indoor or protected environments where corrosion resistance is not a primary requirement.

This washer is used across a wide range of trade applications including HVAC equipment mounting, plumbing fixture installation, electrical panel and enclosure assembly, and general structural fastening. The USS flat washer series is a standard hardware item commonly stocked by mechanical contractors, maintenance technicians, and industrial assemblers. The 100-piece minimum order quantity makes this box format practical for service vans, shop bins, and job site kits where bulk hardware is consumed regularly.

Key Features

• USS pattern with 1-3/8 inch outer diameter for wide load distribution
• 9/16 inch inner diameter fits standard 1/2 inch fasteners with proper clearance
• 7/64 inch thickness provides consistent stack height in fastener assemblies

Compatibility

Designed for use with 1/2 inch screws and bolts conforming to USS flat washer dimensional standards in inch-measurement fastener assemblies.

Installation Notes

Install this washer between the fastener head or nut and the mating surface to distribute clamping load. Ensure the washer inner diameter clears the fastener shank without binding before torquing. In applications subject to moisture or corrosive environments, consider a coated or stainless alternative, as the plain steel finish offers no corrosion protection. Follow applicable mechanical codes and fastener manufacturer specifications for proper torque and assembly procedures.
