Value Collection R52000122 Uss Flat Washer 1 in Steel

Product Description

The VALUE COLLECTION R52000122 is a USS flat washer designed for use with 1-inch screws and bolts. Constructed from steel with a zinc-plated finish, this washer provides corrosion resistance in general-purpose fastening applications. It features a 1-1/16 inch inside diameter, a 2-1/2 inch outside diameter, and a thickness of 0.1719 inches. The wider bearing surface of the USS standard profile distributes load across a larger area than SAE washers, making it suitable for softer substrates and applications where pull-through resistance is a priority. Installers in HVAC, plumbing, electrical, and general mechanical trades keep USS flat washers on hand as standard hardware stock.

This washer is used wherever a 1-inch fastener requires load distribution or surface protection. Common applications include structural connections, equipment mounting, panel fastening, and mechanical assemblies in both residential and commercial settings. The zinc plating provides a baseline level of corrosion resistance appropriate for indoor and moderately protected outdoor environments. Sold individually, this washer suits low-quantity service work and repair jobs where a full box quantity is not needed.

Key Features

• USS flat washer profile provides wider load distribution compared to SAE standard

Compatibility

Designed for use with 1-inch USS-standard screws, bolts, and threaded fasteners. Suitable for general-purpose mechanical, structural, and equipment-mounting applications across multiple trades.

Installation Notes

Install with standard hand tools or impact driver setups appropriate for the fastener being used. Ensure the washer seats flat against the mating surface before torquing the fastener. Zinc plating is suitable for dry or mildly humid environments — do not use in direct water immersion or highly corrosive chemical exposure without verifying suitability. Follow applicable mechanical or structural codes for the specific application.
