Value Collection 31WUSSGPK Uss Flat Washer 5/16 Inch Steel

Product Description

The VALUE COLLECTION 31WUSSGPK is a USS flat washer designed to distribute load evenly under bolt heads and nuts in general fastening applications. Manufactured from steel with a galvanized finish for corrosion resistance, it follows the ASME B18.22.1 standard for USS washer dimensions. The washer measures 3/8 inches inside diameter, 7/8 inches outside diameter, and 5/64 inches thick, making it a reliable fit for 5/16 inch screw sizes. Licensed trades and contractors rely on this type of washer in structural, mechanical, and utility connections where a wider bearing surface is required.

This washer is suited for use in residential and light commercial construction, mechanical assemblies, HVAC equipment mounting, plumbing support strut systems, and general maintenance work. The galvanized finish provides baseline protection against rust in moderately wet or outdoor environments. It is sold in a minimum order quantity of 100 pieces, making it appropriate for stocking on service trucks or in shop inventory where high-volume fastener use is expected.
