Value Collection AHFW088OY Uss Flat Washer 7/8 in Steel

Product Description

The VALUE COLLECTION AHFW088OY is a USS flat washer designed for use with 7/8-inch screws and bolts. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this washer provides corrosion resistance while distributing load across the fastener bearing surface. The USS (United States Standard) series features a larger outer diameter relative to screw size compared to SAE washers, making it the right choice when extra load distribution is needed. Installation requires no special tools and takes seconds. Plumbers, electricians, HVAC technicians, and general contractors reach for this washer in structural and mechanical assemblies where a wide bearing surface is needed.

This washer fits standard 7/8-inch fastener applications across residential and commercial construction, mechanical equipment mounting, HVAC equipment installation, and general trade work. The yellow dichromate zinc coating provides a serviceable corrosion barrier suitable for indoor and protected outdoor applications. The USS standard geometry makes it a common choice for bolted connections in equipment bases, pipe supports, and structural brackets where the wider OD helps prevent pull-through on softer substrate materials.

Key Features

• USS flat washer series — wider OD for greater load distribution than SAE equivalents
• Grade 8 steel construction for high tensile strength applications
• Zinc yellow dichromate finish for corrosion resistance in typical indoor and protected environments
• 15/16-inch ID fits cleanly over 7/8-inch fastener shanks
• 2-1/4-inch OD provides broad bearing surface to reduce pull-through
• 11/64-inch thickness delivers solid, non-deforming performance under load

Compatibility

Designed for use with 7/8-inch screws and bolts conforming to USS flat washer dimensional standards. Suitable for use with standard hex bolts, hex cap screws, and carriage bolts of the corresponding screw size.

Installation Notes

Install between the fastener head or nut and the mating surface to distribute clamping load. Ensure the washer ID seats cleanly over the bolt shank without forcing. Verify that the zinc dichromate finish is compatible with the installation environment before use in direct-contact or submerged conditions. No special tools are required beyond standard wrenches or sockets appropriate to the fastener being used.
