Value Collection R52000135 Uss Flat Washer 9/16 in

Product Description

The VALUE COLLECTION R52000135 is a USS flat washer designed for use with 9/16-inch screws and bolts. Constructed from steel with a zinc-plated finish, it provides corrosion resistance for general fastening applications in mechanical, plumbing, electrical, and HVAC installations. The washer measures 5/8 inches inside diameter, 1-1/2 inches outside diameter, and 0.1094 inches thick, conforming to USS (United States Standard) dimensional specifications. Tradespeople and maintenance technicians rely on USS flat washers to distribute load, prevent surface damage, and protect fastener heads against pull-through on standard assemblies.

This washer is suited for residential and light commercial applications where a standard inch-measurement fastener is used. Typical uses include equipment mounting, panel securing, pipe hanger assemblies, and general mechanical fastening throughout HVAC, plumbing, and electrical installations. The USS series is characterized by a larger outside diameter relative to screw size compared to SAE washers, making it the preferred choice when broader load distribution is needed on softer materials or oversized clearance holes.

Installation Notes

Installation requires no specialized tools beyond standard hand or power wrenches appropriate to the fastener being used. Always ensure the fastener and washer are compatible in material to avoid galvanic corrosion in wet or outdoor environments. Follow applicable mechanical and building codes when securing structural or load-bearing connections. Inspect washers for deformation or coating damage before reuse.
