Value Collection 31314 Uss Flat Washer 1-1/2 in Steel

Product Description

The VALUE COLLECTION 31314 is a USS-pattern flat washer designed for use with 1-1/2 inch fasteners in general industrial, mechanical, and structural applications. Manufactured from steel with a zinc-plated finish, this washer provides corrosion resistance suitable for standard indoor and light-duty outdoor use. It measures 1-5/8 inches inside diameter, 3-1/2 inches outside diameter, and 0.153 inches thick. The USS pattern follows a wider outer diameter standard compared to SAE washers, distributing load more effectively over a broader bearing surface. Plumbers, electricians, HVAC technicians, and maintenance professionals routinely use USS washers when fastening equipment, panels, and structural components.

This washer is appropriate for residential and light commercial maintenance tasks, equipment mounting, pipe hangers, duct support, and general mechanical assembly wherever a 1-1/2 inch fastener requires a broad bearing surface. The zinc plating provides a basic protective layer against oxidation, making it suitable for dry or low-moisture environments. Sold individually per package with a minimum order quantity of 10 pieces, this washer fits standard bolt and screw applications requiring USS-specification geometry.

Installation Notes

Install flat washers between the fastener head or nut and the work surface to distribute clamping load and protect the base material. Power down or de-energize any associated equipment before working near electrical or mechanical assemblies. Ensure the washer seats flat against the surface with no debris or burrs underneath. Follow applicable mechanical and structural codes for the specific installation type.
