010910 - Miller 010910 Flat Washer .406 ID x .812 OD Steel Plated (2-Pack)

Precision Hardware for Industrial Welding Equipment

The Miller 010910 Flat Washer is a specialized hardware component designed to meet the rigorous demands of industrial welding environments. Manufactured to strict OEM specifications, this washer serves as a critical element in maintaining the mechanical integrity of Miller welding power sources, wire feeders, and ancillary equipment. The washer features a specific geometry with an inner diameter (ID) of 0.406 inches and an outer diameter (OD) of 0.812 inches, consistent with ANSI .375 standards typically associated with 3/8-inch fasteners. This precise sizing ensures adequate clearance for bolt installation while maximizing the bearing surface area against the mating substrate.

Constructed from high-grade steel, the 010910 washer provides the necessary compressive strength to withstand significant torque loads without deforming. The material is treated with a plating process—indicated by the "Pld" designation—which imparts a protective layer to mitigate oxidation and corrosion. In the context of welding workshops where humidity, thermal cycling, and atmospheric contaminants are common, this corrosion resistance is vital for preventing seized fasteners and ensuring long-term serviceability. The washer's thickness of 0.065 inches is calibrated to provide the correct spacing and stack-up height in precision assemblies, preventing issues related to loose components or vibration-induced fatigue.

Using genuine Miller replacement parts like the 010910 ensures that the fit, form, and function of the hardware match the original engineering design of the machine. Generic hardware store washers often lack the specific dimensional tolerances or material grades required for heavy-duty equipment. By utilizing this OEM flat washer, maintenance personnel can guarantee proper load distribution, protect delicate surface finishes from damage during tightening, and maintain the reliability of the equipment's structural connections. This product is supplied in a package of two, facilitating immediate repair or stock replenishment for preventative maintenance schedules.
