Value Collection 31301 Uss Flat Washer 1/4 in Zinc Steel

Product Description

The VALUE COLLECTION 31301 is a USS flat washer designed for use with 1/4 inch screws and bolts in general industrial, mechanical, and maintenance applications. Manufactured from steel with a zinc-plated finish, this washer provides a broad bearing surface to distribute fastener load and reduce surface damage. It measures 5/16 inches inner diameter, 3/4 inches outer diameter, and 1/16 inch thick. The zinc plating adds a layer of corrosion resistance suitable for indoor and light-duty outdoor use. These washers are sold individually but require a minimum order quantity of 250 units, making them well suited for contractors, maintenance shops, and trades purchasing in bulk.

This USS flat washer is appropriate for residential and commercial maintenance, plumbing rough-in, electrical panel and fixture mounting, HVAC equipment assembly, and general mechanical fastening tasks. The wider outer diameter of the USS standard provides greater load distribution compared to SAE washers of the same screw size, making it a common choice where soft substrates or oversized clearance holes are involved. Suitable for use wherever a 1/4 inch fastener is employed and a broad bearing surface is required.

Key Features

• USS flat washer profile provides wider load distribution than SAE equivalent
• Steel construction with zinc-plated finish for corrosion resistance
• 5/16 inch inner diameter fits standard 1/4 inch screws and bolts with clearance
• 3/4 inch outer diameter distributes clamping load across a broad surface area
• 1/16 inch thickness keeps stack height low in tight fastener assemblies
• Inch measurement system; minimum order quantity of 250 units

Compatibility

Designed as a standard USS flat washer for use with 1/4 inch screws and bolts across general-purpose fastening applications.

Installation Notes

Flat washers are installed by placing them onto the fastener shank between the fastener head or nut and the mating surface before tightening. Always match the washer inner diameter to the fastener diameter and ensure the outer diameter spans any clearance hole fully. Follow applicable torque and fastener specifications for the assembly type per relevant codes. Inspect zinc-plated washers for coating damage before use in corrosion-sensitive environments.
