Value Collection USFW0310100OZ Uss Flat Washer 5/16 in

Product Description

The VALUE COLLECTION USFW0310100OZ is a USS flat washer designed for use with 5/16-inch screws and bolts. Manufactured from steel with a zinc-plated finish, this washer provides a broad bearing surface that distributes fastener load and reduces the risk of pull-through on soft or uneven materials. The zinc coating offers basic corrosion resistance for general indoor and light outdoor applications. With an inside diameter of 3/8 inches, an outside diameter of 7/8 inches, and a thickness of 3/32 inches, this washer conforms to USS (United States Standard) dimensional specifications. Each minimum order covers 100 pieces, making it appropriate for production, maintenance, or job-site stock.

This washer is suited for mechanical assembly, structural fastening, HVAC equipment mounting, plumbing fixture installation, and general construction work. The USS series features a larger outside diameter than SAE washers of the same screw size, providing greater load distribution. It is commonly installed by HVAC technicians, plumbers, electricians, and general contractors wherever a 5/16-inch fastener requires a bearing surface or a standard flat washer is called out in an installation specification.

Key Features

• USS flat washer profile provides wider load-bearing surface than SAE equivalents for the same screw size
• Steel construction delivers reliable mechanical strength for general fastening applications
• Zinc-plated finish offers basic corrosion resistance for light-duty environments
• Sized for 5/16-inch screw with 3/8-inch inside diameter for consistent fit
• Sold in 100-piece minimum order quantity for job-site and maintenance stocking

Compatibility

Designed as a standard USS flat washer for use with 5/16-inch screws and bolts in general mechanical and construction fastening applications.

Installation Notes

Installation requires no specialized tools beyond standard hand or power wrenches. Always ensure the fastener and washer are sized correctly for the application before torquing. For outdoor or high-moisture environments, evaluate whether additional corrosion protection beyond zinc plating is required by the job specification. Follow applicable mechanical or building codes for fastener assembly requirements.
