Value Collection C85881 Uss Flat Washer 7/16 in Steel Zinc

Product Description

The VALUE COLLECTION C85881 is a USS flat washer designed for use with 7/16 inch screws and bolts in general fastening applications. Manufactured from steel with a zinc-plated finish, this washer provides a broad bearing surface to distribute clamping load and reduce the risk of fastener pull-through or surface damage. The zinc coating adds a layer of corrosion resistance suitable for indoor and light-duty outdoor assemblies. With a 1/2 inch inside diameter and a 1-1/4 inch outside diameter, the washer conforms to USS (United States Standard) dimensional standards, making it a reliable choice for structural and mechanical installations where load distribution matters.

This washer is suited for residential and commercial construction, mechanical assemblies, HVAC equipment mounting, plumbing rough-in framing, and general trade work where a standard USS-series flat washer is specified. It is compatible with 7/16 inch fasteners and is commonly installed by carpenters, plumbers, HVAC technicians, electricians, and general contractors during equipment mounting and structural fastening tasks. Sold individually, with a minimum order quantity of 50 pieces.

Installation Notes

Install this washer between the fastener head or nut and the mating surface to distribute load and prevent surface damage. Ensure the fastener shank passes freely through the 1/2 inch inside diameter before torquing. Zinc-plated washers are not recommended for prolonged exposure to highly corrosive environments or direct contact with pressure-treated lumber without a suitable barrier. No special tools are required beyond standard hand or power wrenches appropriate to the fastener size.
