277890 - Miller 6-32 x 1.000 Steel Hex Stand-Off (Pack of 4)

Miller 277890 Stand-Off Replacement Hardware

The Miller 277890 is a specialized hardware component designed for the maintenance and repair of Miller welding power sources and wire feeders. This stand-off features a No. 6-32 thread size with a 1.000-inch length and a 0.250-inch hex body. Constructed from durable steel, it utilizes a Male/Female (M&F) configuration, making it essential for spacing printed circuit boards (PCBs) or other internal components securely within the machine chassis.

As an OEM part, this stand-off ensures precise fitment and maintains the structural integrity of the electrical assemblies inside your equipment. Proper spacing is critical for airflow and electrical isolation in high-performance welding machines. This package contains four (4) stand-offs, allowing technicians to replace multiple worn or missing fasteners during a service interval.

Industrial environments often subject welding machines to vibration and thermal cycling, which can loosen or damage internal hardware over time. Using genuine Miller replacement parts guarantees that the thread pitch and material strength meet the original engineering specifications, preventing stripped threads or component misalignment. Whether you are rebuilding a control board assembly or replacing a single damaged mount, this stand-off provides the reliability required for professional equipment repair.

This item is typically identified in Miller parts breakdowns for various MIG, TIG, and Stick welders. Always verify the part number against your machine's manual to ensure compatibility with your specific model.
