Value Collection USS087 Uss Flat Washer 7/8 in Steel

Product Description

The VALUE COLLECTION USS087 is a USS flat washer designed for use with 7/8-inch fasteners. Made from steel with a plain finish, this washer distributes load across a bearing surface to prevent fastener pull-through, protect workpiece surfaces, and provide a stable clamping interface. The washer measures 15/16 inches inner diameter, 2-1/4 inches outer diameter, and 1.028 inches thick. It meets ASME B18.21.1-2009 standards for inch-series flat washers. Installers, maintenance technicians, and tradespeople working with structural or mechanical fastened connections will find this washer suitable for general-purpose fastening applications.

This USS flat washer is intended for use in mechanical, structural, and industrial assembly contexts where a larger outer diameter is required relative to the screw size. USS-series washers carry a wider OD than SAE-series washers of the same screw size, making them appropriate when load spreading over a larger area is needed. This washer ships individually and is sold per piece, making it practical for single-repair jobs or low-quantity restocking.

Compatibility

Designed for use with 7/8-inch screw fasteners in standard inch-series fastened assemblies requiring a USS flat washer per ASME B18.21.1-2009.

Installation Notes

Install flat washers between the fastener head or nut and the workpiece surface to distribute clamping load and reduce surface damage. Ensure the washer inner diameter clears the fastener shank without excessive play before torquing. Follow applicable fastening standards and project specifications for proper torque values. No special tools are required for installation beyond standard hand or power wrenches.
