Value Collection 99762 Uss Flat Washer 3/8 in Steel

Product Description

The VALUE COLLECTION 99762 is a USS flat washer designed for use with 3/8 inch screws and bolts. Manufactured from Grade 8 steel with a plain finish, this washer distributes load across a bearing surface to prevent fastener pull-through and protect mating materials. The 7/16 inch inner diameter seats cleanly over standard 3/8 inch fasteners, while the 1 inch outer diameter provides a broad clamping surface. This washer follows the USS (United States Standard) dimensional series, which specifies a larger outer diameter than SAE equivalents for applications requiring greater load distribution. Plumbers, HVAC technicians, electricians, and general tradespeople use flat washers like this in structural, mechanical, and utility installations throughout residential and commercial jobsites.

This washer is suited for general fastening applications across trade and light industrial work. The USS dimension series is commonly specified when a wider bearing surface is needed compared to SAE flat washers of the same nominal screw size. Typical use cases include equipment mounting, pipe hanger assemblies, panel attachment, and structural connections where load spreading is required. The plain steel finish is appropriate for interior or protected installations where corrosion resistance is not a primary concern.

Installation Notes

Flat washers are installed by any trade professional handling mechanical fastening tasks. Always ensure the washer inner diameter is compatible with the fastener shank before assembly. For structural or load-bearing connections, verify washer grade and dimension requirements against applicable codes such as the IBC or applicable mechanical codes. Plain steel washers should not be used in wet, outdoor, or corrosive environments without additional corrosion protection measures.
