Value Collection 36773 Uss Flat Washer 7/8 in Steel

Product Description

The VALUE COLLECTION 36773 is a USS-pattern flat washer designed for 7/8-inch screw sizes in standard inch-measurement fastener applications. Stamped from Grade 8 steel and finished with a zinc yellow dichromate coating, this washer provides a broad bearing surface to distribute clamp load and reduce fastener pull-through in structural and mechanical assemblies. The zinc yellow dichromate finish adds a layer of corrosion resistance suited to general industrial and outdoor service environments. Typical installers include millwrights, ironworkers, pipefitters, and maintenance technicians working with heavy structural bolted connections.

This washer is used wherever a USS-series large-OD flat washer is required alongside 7/8-inch bolts or screws. USS flat washers carry a larger outer diameter than SAE counterparts of the same nominal screw size, making them the preferred choice when bearing surface area matters — such as through-bolted wood, sheet metal, or softer substrates. Typical applications include structural steel connections, equipment mounting, pipe support bracketing, and general mechanical assembly in residential, commercial, and light industrial settings.

Key Features

• USS flat washer pattern — larger OD than SAE for increased load distribution
• Fits 7/8-inch nominal screw or bolt size
• Grade 8 steel construction for high-strength bolted joint applications
• Zinc yellow dichromate finish for corrosion resistance in general service environments
• Inside diameter of 15/16 inches provides proper clearance for 7/8-inch fasteners
• Outside diameter of 2-1/4 inches and thickness of 11/64 inches conform to USS dimensional standards

Compatibility

Designed for use with 7/8-inch USS-pattern bolted connections in standard inch-measurement assemblies requiring a large-OD flat washer.

Installation Notes

Install with the washer seated flat against the mating surface before torquing the fastener to the joint specification. Ensure the bearing surface is clean and free of debris to maintain even load distribution. No special tooling is required beyond standard wrenches or impact equipment appropriate to the fastener grade. Follow applicable codes and engineering specifications for the bolted joint being assembled.
