Value Collection C85888 Uss Flat Washer 1-1/8 in Steel

Product Description

The VALUE COLLECTION C85888 is a USS flat washer designed for use with 1-1/8 inch screws and bolts. Manufactured from Grade 8 steel with a zinc-plated finish, this washer distributes load across the fastener bearing surface and helps protect the mating material from damage during assembly. The zinc coating provides a baseline level of corrosion resistance suitable for general-purpose indoor and light-duty applications. With an inside diameter of 1-1/4 inches, an outside diameter of 2-3/4 inches, and a thickness of 5/32 inches, it conforms to USS dimensional standards for oversized flat washers.

This washer is suited for structural and mechanical assembly work where a larger bearing surface is required under a bolt head or nut. Common applications include general fabrication, equipment maintenance, and construction fastening tasks performed by millwrights, pipefitters, maintenance technicians, and general contractors. The USS series provides a wider OD-to-screw-size ratio compared to SAE washers, making it the preferred choice when load distribution across a larger surface area is needed.

Key Features

• USS flat washer standard — wider OD for increased load distribution versus SAE washers
• Grade 8 steel construction for high-strength fastening applications
• Zinc-plated finish for corrosion resistance in general-purpose environments
• Inside diameter of 1-1/4 inches fits 1-1/8 inch screw or bolt shank
• Outside diameter of 2-3/4 inches provides broad bearing surface
• Thickness of 5/32 inches for consistent load transfer and dimensional stability

Compatibility

Designed as a standard USS flat washer for use with 1-1/8 inch fasteners in general mechanical and structural assembly applications.

Installation Notes

Install using standard hand tools appropriate for the fastener size. Ensure the washer seats flush against the mating surface before applying torque to the fastener. Inspect the zinc coating for damage prior to installation in environments where corrosion resistance is critical. Follow applicable mechanical assembly standards and any project-specific fastener specifications.
