Overview

Minerallac 40335P 3/8" USS Flat Washers are precision-engineered low-carbon steel washers designed for industrial assembly applications requiring uniform load distribution and corrosion resistance. Each washer features a 0.080" thickness with an outside diameter optimized for 3/8" bolt sizes, ensuring compatibility with standard fasteners in electrical, mechanical, and structural assemblies. The zinc-plated finish provides reliable protection against rust and corrosion, extending service life in harsh environments. Supplied in a 2000-piece pail, these washers are ideal for high-volume installations where consistent quality and bulk packaging streamline procurement and reduce downtime. Compliance with RoHS standards confirms environmental safety, while the Minerallac brand guarantees adherence to rigorous manufacturing tolerances. Commonly used in electrical enclosures, panel assemblies, and machinery mounting, these washers improve joint integrity by reducing stress concentrations around bolt holes. The flat cut design ensures a snug fit against mating surfaces, preventing loosening under vibration. For applications requiring alternative packaging or specialized finishes, Minerallac offers related part numbers such as 40335J (jar-packed) and 40335USJ (through-hardened zinc-plated).
