Value Collection C39875 Uss Flat Washer 1/2 in Steel Zinc

Product Description

The VALUE COLLECTION C39875 is a USS flat washer designed for use with 1/2 inch screws and bolts. Manufactured from Grade 8 steel with a zinc-plated finish, this washer distributes load across the fastener bearing surface to protect the mating material and reduce the risk of pull-through or surface damage. The zinc coating provides corrosion resistance suited to general-purpose indoor and light industrial applications. It measures 9/16 inches inner diameter, 1-3/8 inches outer diameter, and 7/64 inches thick, conforming to USS (United States Standard) flat washer dimensions. Installed by maintenance technicians, pipefitters, electricians, and general tradespeople wherever a standard 1/2 inch fastener assembly is required.

This washer is appropriate for a wide range of trade and industrial assembly applications including HVAC equipment mounting, electrical enclosure assembly, plumbing fixture installation, and general structural fastening. The USS flat washer series uses a larger outer diameter relative to SAE flat washers of the same screw size, making it the preferred choice when additional load-bearing surface area is needed. Sold individually with a minimum order quantity of 100 pieces.

Always de-energize electrical systems and relieve pressure from plumbing or HVAC systems before disassembling fastened joints. Use appropriate hand tools and torque specifications as defined by the equipment manufacturer or applicable code. Do not substitute washer sizes without verifying that the replacement meets the load and dimensional requirements of the original fastener assembly.
