Value Collection 99772 Uss Flat Washer 1-1/2 in Steel

Product Description

The VALUE COLLECTION 99772 is a USS flat washer designed for use with 1-1/2 inch screws and bolts. Manufactured from steel with a plain finish, this washer distributes load across the fastener bearing surface to reduce pull-through and protect the mated material. The 99772 features a 1-5/8 inch inside diameter and a 3-1/2 inch outside diameter, conforming to USS (United States Standard) dimensional specifications. It is sold individually with a minimum order quantity of 10 pieces. Licensed tradespeople and maintenance professionals use flat washers in structural, mechanical, and utility fastening applications across a wide range of industries.

This washer is suited for general-purpose fastening tasks in construction, HVAC equipment mounting, plumbing rough-in work, electrical panel installation, and industrial maintenance. The USS flat washer series is characterized by a larger outside diameter relative to SAE-series washers of the same screw size, making it a preferred choice when a broader bearing surface is required or when fastening into softer or lower-density base materials.

Installation Notes

Flat washers are installed by tradespeople and maintenance technicians as part of standard bolted or screwed connections. Always ensure the inside diameter clears the fastener shank without excessive play. The plain finish on this washer provides no corrosion protection, so it should not be used in wet, outdoor, or corrosive environments without additional protective measures. Follow applicable building codes and equipment manufacturer torque guidelines when assembling fastened joints.
