4770 - Miller 4770 Replacement Screw 6-32 x 1/4

Genuine Miller 4770 Replacement Screw

The Miller 4770 is a specific machine screw designed for use within Miller Electric welding power sources, wire feeders, and auxiliary equipment. As a genuine OEM (Original Equipment Manufacturer) component, this screw is engineered to meet the precise dimensional and material specifications required for Miller machinery. It features a standard 6-32 NC (National Coarse) thread pitch and a length of 1/4 inch. While fasteners may seem like minor components, using the correct specification is critical in industrial equipment to ensure proper assembly, grounding, and vibration resistance.

In the context of welding machine maintenance, the integrity of every connection matters. The 6-32 thread size is a common standard for mounting electrical components, circuit boards, and smaller chassis panels. Using a screw with the correct hardness and thread profile prevents damage to the mating tapped holes or nuts, which can be costly to repair if stripped. The 1/4 inch length is specifically chosen to provide adequate thread engagement without extending too far into the machine, where it could potentially contact live electrical circuits or moving parts.

Technicians repairing Miller equipment should always verify the part number in the machine's service manual. The Miller 4770 is often utilized in various assemblies across different model lines. Whether you are replacing a lost fastener during routine maintenance or rebuilding a unit after a repair, opting for the authentic Miller part guarantees that the hardware matches the original factory build quality. This screw is sold individually, allowing maintenance personnel to order the exact quantity needed for the job at hand.

Proper torque application is recommended when installing these screws to avoid over-tightening, especially when securing sensitive electronic components or sheet metal covers. By maintaining your equipment with genuine Miller parts, you ensure the longevity and reliability of your welding investment.
