Value Collection R52000112 Uss Flat Washer 1/4 in

Product Description

The VALUE COLLECTION R52000112 is a USS flat washer designed for use with 1/4-inch screws and bolts. Manufactured from steel with a zinc-plated finish, this washer provides corrosion resistance in a wide range of fastener applications. The USS (United States Standard) pattern features a larger outer diameter relative to the screw size compared to SAE washers, distributing clamping load over a broader surface area. With a 5/16-inch inner diameter, 3/4-inch outer diameter, and 1/16-inch thickness, this washer suits standard structural and mechanical assembly work across plumbing, HVAC, electrical, and general trade applications.

This USS flat washer is appropriate for residential and light commercial installations where a 1/4-inch fastener is used and load distribution or surface protection is required. Common use cases include equipment mounting, panel attachment, pipe support brackets, and general mechanical assembly. The zinc plating makes it suitable for mildly corrosive or outdoor-adjacent environments where bare steel would be insufficient. It is sold individually and is compatible with standard 1/4-inch bolts, screws, and threaded rod commonly found in trade work.

Key Features

• USS flat washer pattern for wider load distribution than SAE equivalents
• Steel construction with zinc-plated finish for corrosion resistance
• 5/16-inch inner diameter fits standard 1/4-inch screw and bolt shanks
• 3/4-inch outer diameter provides broad bearing surface
• 1/16-inch thickness suits standard fastener stack-ups
• Inch measurement system for compatibility with standard US fasteners

Compatibility

Designed for use with 1/4-inch screws, bolts, and threaded rod in standard inch-measurement fastener assemblies across HVAC, plumbing, electrical, and general mechanical applications.

Installation Notes

Install with the washer seated flat against the mating surface before driving the fastener. Ensure the inner diameter clears the fastener shank without binding. For outdoor or high-moisture installations, verify the zinc-plated finish meets the corrosion resistance requirements of the application or supplement with additional corrosion protection as needed. No special tools are required for installation.
