Value Collection AHFW150OY Uss Flat Washer 1-1/2 in Steel

Product Description

The VALUE COLLECTION AHFW150OY is a USS-pattern flat washer designed for use with 1-1/2 inch screws and bolts. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this washer provides corrosion resistance and a wide bearing surface suited to distribute load across fastened assemblies. It measures 1-5/8 inches inside diameter, 3-1/2 inches outside diameter, and 3/16 inches thick. The USS flat washer pattern specifies a larger outer diameter than SAE-pattern washers, making it appropriate where extra load distribution or surface protection is needed. Tradespeople and maintenance professionals install these in structural, mechanical, and industrial fastening applications.

This washer is used in a wide range of commercial and industrial applications where 1-1/2 inch fasteners are present. Typical install scenarios include structural bolted connections, machinery mounting, HVAC equipment anchoring, plumbing fixture support, and general mechanical assembly. The Grade 8 steel construction and yellow dichromate coating make it suitable for both indoor and moderate-exposure environments where mild corrosion resistance is required. Sold in minimum order quantities of 25 pieces per order.

Installation Notes

Install using standard hand tools appropriate for the fastener size; no specialized tooling is required for washer placement. Always power down or de-energize equipment and relieve system pressure before performing any fastening or maintenance work on mechanical or HVAC assemblies. Position the washer between the fastener head or nut and the mating surface to distribute clamping load and prevent surface damage. Follow applicable codes and torque specifications provided by the equipment manufacturer or governing installation standard.
