Value Collection C39871 Uss Flat Washer 1/4 in Steel

Product Description

The VALUE COLLECTION C39871 is a USS flat washer designed for use with 1/4 inch screws and bolts. Manufactured from Grade 8 steel with a zinc-plated finish, this washer distributes load across fastened surfaces and helps prevent pull-through and surface damage. The zinc plating provides a basic level of corrosion resistance suitable for general-purpose indoor and light outdoor applications. With a 5/16 inch inside diameter, 3/4 inch outside diameter, and 1/16 inch thickness, it conforms to USS (United States Standard) dimensional specifications. Plumbers, electricians, HVAC technicians, and general contractors use USS flat washers as part of routine mechanical assembly and equipment installation.

This washer suits a wide range of trade and industrial applications where a standard 1/4 inch fastener is used. Common uses include securing equipment brackets, mounting panels, assembling pipe hangers, and general structural fastening in both residential and light commercial settings. The USS series features a larger outside diameter than SAE washers of the same screw size, making it the preferred choice when greater load distribution is needed on softer or composite surfaces.

Compatibility

Designed as a standard USS flat washer for use with 1/4 inch fasteners in general mechanical, electrical, plumbing, and HVAC assembly applications.

Installation Notes

Install using standard hand tools appropriate to the fastener type. Ensure the washer seats flat against the mating surface before tightening. Do not use zinc-plated washers in submerged or highly corrosive environments where a stainless or hot-dip galvanized finish would be more appropriate. Follow applicable mechanical or structural codes for the specific assembly being performed.
