Value Collection 99769 Uss Flat Washer 1 Inch Steel

Product Description

The VALUE COLLECTION 99769 is a USS flat washer designed for use with 1-inch screws and fasteners. Made from steel with a plain finish, this washer distributes load across a bearing surface to protect the material being fastened and reduce the risk of pull-through. The USS pattern specifies a larger outside diameter relative to the screw size compared to standard SAE washers, making it well suited for applications where added bearing surface is needed. It measures 1-1/16 inches inner diameter and 2-1/2 inches outer diameter. Plumbers, electricians, HVAC technicians, and general trade contractors use USS flat washers routinely in mechanical and structural fastening tasks.

This washer is appropriate for residential and light commercial applications where a 1-inch fastener is used on steel, wood, or composite substrates. The plain finish makes it suitable for dry or protected indoor environments. The USS designation follows inch-system dimensional standards, and the material grade 8 rating indicates a higher-strength steel suitable for demanding fastening assemblies. Supplied individually, with a minimum order quantity of 20 pieces.

Installation Notes

USS flat washers are installed by general trade professionals and mechanical contractors using standard hand or power tools. Place the washer over the fastener shank before seating the nut or bolt head to distribute clamping load. Plain-finish steel washers should not be used in wet, outdoor, or corrosive environments without additional corrosion protection. Follow applicable mechanical and building codes for fastener assembly torque and material compatibility.
