Value Collection 99766 Uss Flat Washer 5/8 in Steel

Product Description

The VALUE COLLECTION 99766 is a USS flat washer designed for use with 5/8 inch screws and bolts in standard fastening applications. Manufactured from steel with a plain finish, this washer distributes load across the fastening surface to reduce the risk of pull-through and surface damage. The 11/16 inch inside diameter seats cleanly over a 5/8 inch fastener, while the 1-3/4 inch outside diameter provides broad bearing coverage. Electricians, plumbers, HVAC technicians, and general trade contractors use USS flat washers daily in panel mounting, equipment installation, and structural connections.

USS flat washers follow the United States Standard (USS) dimensional series, which specifies a wider outside diameter than SAE washers of the same screw size. This wider footprint makes them appropriate for use with softer base materials, oversized holes, and applications where load spread is a priority. The plain steel finish suits interior and dry-service applications. This washer is sold individually but requires a minimum order of 50 pieces per transaction.

Compatibility

Designed as a standard USS-series flat washer compatible with 5/8 inch fasteners in general mechanical, structural, and trade installation applications where USS dimensional specifications are required.

Installation Notes

USS flat washers are installed by general trade and mechanical contractors as part of bolted connections. Always verify the washer inside diameter clears the fastener shank without binding before assembly. Plain steel finish is not suitable for outdoor or wet environments where corrosion resistance is required. Follow applicable building, mechanical, or electrical codes for fastener assembly torque and connection specifications.
