602239 - Miller Steel Plated Flat Washer .250 ID x .562 OD

Miller 602239 Flat Washer Overview

The Miller 602239 Flat Washer is a genuine Original Equipment Manufacturer (OEM) component designed specifically for the maintenance and repair of Miller welding machines and industrial equipment. Precision engineering is critical in the assembly of high-performance welding power sources, and even small hardware components like washers play a vital role in the structural integrity and longevity of the machine. This specific washer features an Inner Diameter (ID) of 0.250 inches, making it compatible with standard 1/4-inch fasteners often found throughout Miller's product lines.

Constructed from high-quality steel, this washer is plated to provide essential resistance against corrosion and oxidation. In industrial environments where welding equipment is exposed to humidity, temperature fluctuations, and atmospheric contaminants, plated hardware ensures that the fastener assembly remains secure and free from rust seizure over time. The Outer Diameter (OD) of 0.562 inches provides a substantial surface area to distribute the load of the fastener head or nut, preventing damage to the underlying surface and reducing the risk of the fastener pulling through under stress.

With a thickness of 0.065 inches, the Miller 602239 maintains a low profile while offering sufficient rigidity to act as a reliable spacer or bearing surface. Using non-OEM hardware from general hardware stores can often lead to fitment issues, as generic washers may have wider tolerances or different metallurgical properties that do not match the specific requirements of the welding machine's design. By choosing the genuine Miller 602239 washer, operators and technicians ensure that every part of their equipment meets the manufacturer's rigorous standards for safety and performance.

This component is essential for technicians performing routine maintenance, chassis repairs, or internal component replacements. Whether securing circuit boards, sheet metal panels, or internal brackets, the correct washer ensures that vibration from the welding process does not loosen critical connections. Investing in genuine Miller parts guarantees that the equipment remains within factory specifications, preserving the value and reliability of the welding system.
