The VALUE COLLECTION C39877 is a USS flat washer designed for 3/4-inch screw applications. Manufactured from steel with a zinc-plated finish, this washer provides corrosion resistance and load distribution under fastener heads and nuts. The USS (United States Standard) pattern features a larger outside diameter relative to screw size, making it well suited for spreading clamp load across softer or thinner materials. With an inside diameter of 13/16 inches, an outside diameter of 2 inches, and a thickness of 9/64 inches, this washer meets standard USS dimensional specifications. It is installed by electricians, plumbers, HVAC technicians, pipefitters, and general tradespeople wherever a wide-bearing flat washer is required.
This washer is appropriate for use in residential and commercial construction, mechanical assemblies, electrical panel work, plumbing rough-in, HVAC equipment mounting, and structural fastening applications. The zinc-plated steel construction makes it suitable for interior and moderately exposed environments. It is sold individually but requires a minimum order quantity of 50 units, making it practical for stocking in trade shops, service vehicles, or job-site supply kits.
Designed as a standard USS-pattern flat washer for use with 3/4-inch screws and bolts in inch-measurement fastening systems across commercial and residential trade applications.
Flat washers are installed by placing them over the fastener shank before driving the nut or bolt head. Ensure the fastener and washer grade ratings are compatible with the joint requirements. No special tools are required for installation. Follow applicable mechanical and structural codes for proper fastener assembly torque and joint design.
