Value Collection C85884 Uss Flat Washer 5/8 Inch Steel

Product Description

The VALUE COLLECTION C85884 is a USS flat washer designed for use with 5/8-inch screws and bolts. Manufactured 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 zinc coating provides a baseline layer of corrosion resistance suitable for general indoor and light-duty applications. With an inside diameter of 11/16 inches, an outside diameter of 1-3/4 inches, and a thickness of 9/64 inches, this washer conforms to USS (United States Standard) dimensional specifications. Licensed tradespeople and maintenance professionals keep these on hand as a standard hardware consumable.

This USS flat washer is suited for residential and commercial mechanical, electrical, and structural fastening tasks where a 5/8-inch fastener is used. Common applications include equipment mounting, pipe support bracketing, ductwork hangers, and general mechanical assembly. The USS standard specifies a larger outer diameter than SAE washers of the same screw size, making this washer the appropriate choice when extra load-bearing surface area is needed. Sold individually with a minimum order quantity of 25 pieces.

Key Features

• USS standard sizing with 11/16-inch ID and 1-3/4-inch OD for broad load distribution
• Grade 8 steel construction for high-strength fastening applications
• Zinc-plated finish for basic corrosion resistance in dry and low-humidity environments
• 9/64-inch thickness provides rigidity under clamping load
• Inch measurement system, compatible with standard US fastener hardware

Compatibility

Designed for use with 5/8-inch USS-standard screws and bolts across general mechanical, HVAC, plumbing, and electrical installation applications where USS flat washer dimensions are specified.

Installation Notes

Install with the washer seated flat against the work surface under the fastener head or nut before torquing. Ensure the fastener shank diameter does not exceed the washer inside diameter. Power down or de-energize any equipment before servicing fastened assemblies on live systems. Use appropriate hand tools and follow applicable codes such as NEC or IFGC when installing fasteners in trade system applications.
