Miller 188098 Replacement Shoulder Washer

The Miller 188098 is a high-quality nylon shoulder washer designed for use in various Miller welding machines. As a genuine replacement part, it guarantees the dimensional accuracy required for sensitive internal assemblies. Shoulder washers are indispensable in electronics and heavy machinery where a screw or bolt must be electrically isolated from the surface it passes through. The shoulder of this washer fits into the mounting hole, preventing the fastener's shank from touching the sides, while the flange prevents the head from making contact with the surface.

Constructed from robust nylon, this washer offers a combination of toughness and flexibility. Nylon is chosen for its non-conductive properties, making it the standard for electrical isolation in welding power sources. It also provides a degree of vibration dampening, which helps prevent fasteners from loosening over time due to the hum and rumble of the transformer or fan operations. Using non-OEM substitutes with incorrect tolerances can result in poor fitment, compromised insulation, or cracked washers during installation.

Technical Specifications and Fitment

This washer features an inner diameter of 0.192 inches, making it suitable for specific screw sizes used in Miller equipment. The flange has an outer diameter of 0.375 inches and a thickness of 0.047 inches, providing a sufficient bearing surface for the fastener head. The shoulder portion, which inserts into the mounting hole, has an outer diameter of 0.245 inches and a depth of 0.047 inches. Please verify these dimensions against your service manual or the part you are replacing to ensure compatibility.

Installation Tip: When installing nylon washers, care should be taken not to over-torque the fastener. While nylon is durable, excessive force can crush the material, reducing its insulating effectiveness. Hand-tightening or using a torque wrench to manufacturer specifications is recommended. Keep your Miller welder operating at peak safety and efficiency with this authentic replacement component.
