Value Collection 39756 5/8 in Uss Flat Washer Carbon Steel

Product Description

The VALUE COLLECTION 39756 is a USS flat washer designed for use with 5/8-inch fasteners in general mechanical, plumbing, and structural assembly applications. Manufactured from carbon steel with a zinc yellow dichromate finish, this washer provides a wider bearing surface than standard SAE washers, distributing load more evenly across the joint face. The yellow dichromate coating adds a base level of corrosion resistance and helps the fastener assembly meet common industrial finishing requirements. Material Grade 9 construction delivers reliable hardness and dimensional consistency across the lot. This washer is sold individually with a minimum order quantity of 50 pieces.

USS flat washers are commonly used in residential and light commercial construction, HVAC equipment mounting, plumbing rough-in work, and general equipment assembly wherever a large-diameter, low-profile washer is specified. The 5/8-inch screw size fits standard USS washer dimensions per inch system specifications, making it interchangeable with other USS-spec washers of the same screw size designation.

Key Features

• USS pattern provides a larger outer diameter than SAE equivalents for improved load distribution
• Carbon steel construction with Material Grade 9 for consistent hardness and dimensional accuracy
• Zinc yellow dichromate finish for baseline corrosion and oxidation resistance
• Inch system dimensions — fits 5/8-inch fasteners per USS washer standards
• Sold per piece with a minimum order quantity of 50 units

Compatibility

Designed as an OEM-style replacement or general-use USS flat washer for 5/8-inch screw and bolt fastener assemblies in inch-measurement applications.

Installation Notes

USS flat washers are installed by plumbers, HVAC technicians, electricians, and general tradespeople as part of bolted or screwed joint assemblies. Always power down or de-energize equipment before accessing fastener assemblies on electrical or mechanical systems. Inspect the washer seating surface for debris or corrosion before torquing fasteners. Do not substitute a USS washer for an SAE washer in applications where the outer diameter is tolerance-critical without verifying dimensional specs against the engineering drawing.
