Value Collection C712054 Uss Flat Washer 1-1/2 in Steel

Product Description

The VALUE COLLECTION C712054 is a USS flat washer designed for use with 1-1/2 inch screws and bolts. Constructed from Grade 8 steel with a zinc-plated finish, this washer distributes load across the fastener head or nut, reducing surface damage and preventing pull-through on softer substrates. The inside diameter measures 1-5/8 inches, the outside diameter is 3-1/2 inches, and the thickness is 13/64 inches. These dimensions conform to USS (United States Standard) flat washer specifications, which call for a larger OD relative to the screw size compared to SAE washers. Installers across mechanical, structural, and industrial applications rely on this standard sizing for general-purpose fastening work.

This washer is suited for use in residential and commercial construction, mechanical assemblies, and industrial maintenance applications where a 1-1/2 inch fastener is used. The USS series is a common choice when a wider bearing surface is needed to spread clamping load over wood, sheet metal, or structural members. The zinc-plated finish provides basic corrosion resistance suitable for indoor and sheltered outdoor environments. Sold individually with a minimum order quantity of 5 units.

Key Features

• USS flat washer pattern — wider OD provides greater load distribution than SAE equivalents at the same screw size
• Grade 8 steel construction for high-strength fastening applications
• Zinc-plated finish for basic corrosion resistance in dry and sheltered environments
• 1-5/8 inch ID fits standard 1-1/2 inch screw and bolt shanks with appropriate clearance
• 3-1/2 inch OD and 13/64 inch thickness meet USS dimensional standards
• Inch measurement system — compatible with standard imperial fastener assemblies

Compatibility

Designed for use with 1-1/2 inch screws and bolts conforming to USS flat washer dimensional standards in general-purpose imperial fastener assemblies.

Installation Notes

Install with the washer seated flat against the bearing surface beneath the bolt head or nut before torquing. Ensure the fastener shank passes freely through the 1-5/8 inch ID without binding. For structural or load-bearing applications, consult applicable building codes and engineering specifications for proper fastener assembly requirements. Inspect the zinc coating for damage before installation in environments with moisture exposure.
