Value Collection 31309 Uss Flat Washer 7/8 in Steel Zinc

Product Description

The VALUE COLLECTION 31309 is a USS flat washer designed for use with 7/8 inch screws and bolts. Manufactured from Grade 2 steel with a zinc-plated finish, this washer distributes load across a broader surface area to protect fastened materials and reduce the risk of pull-through. The 15/16 inch inner diameter, 2-1/4 inch outer diameter, and 11/64 inch thickness conform to USS (United States Standard) dimensional standards. It is a standard hardware component installed by contractors, maintenance technicians, and tradespeople across plumbing, mechanical, and structural applications.

This washer is suited for general-purpose fastening tasks in residential and commercial construction, mechanical rooms, and equipment mounting applications. The zinc plating provides baseline corrosion resistance appropriate for indoor and dry-environment use. Typical installations include bolt assemblies on structural supports, pipe hangers, equipment bases, and utility mounting hardware where a larger bearing surface is required under a fastener head or nut.

Key Features

• USS flat washer standard — larger outer diameter for maximum load distribution
• Grade 2 steel construction for reliable tensile strength in general-purpose use
• Zinc-plated finish provides corrosion resistance in dry and low-moisture environments
• 15/16 inch inner diameter fits 7/8 inch screw or bolt shank with standard clearance
• 2-1/4 inch outer diameter and 11/64 inch thickness meet USS dimensional specifications

Compatibility

Designed as an OEM-style replacement or standard-use flat washer for 7/8 inch fastener assemblies where USS dimensions are specified.

Installation Notes

Install using standard hand tools; no specialized equipment is required for washer placement. Position the washer between the fastener head or nut and the mating surface before torquing. Zinc-plated finish is intended for dry or low-moisture indoor environments — avoid use in continuously wet or highly corrosive conditions without an appropriate coating or material upgrade. Verify USS dimensional requirements against the application specification before installation.
