058420 - Miller 1/4-20 x 0.56 Knurled Thumb Screw, Plated Steel

Genuine Miller 058420 Knurled Thumb Screw

Maintain the integrity and functionality of your Miller welding equipment with the genuine Miller 058420 Screw, .250-20X .56 Thumb Knurled Stl Pld. As an original equipment manufacturer (OEM) component, this screw is engineered to meet the precise specifications required for Miller machines, ensuring a seamless fit and reliable performance. In the demanding environment of a welding shop, hardware can often become lost, stripped, or corroded. Replacing these small but vital components with authentic parts guarantees that your equipment remains safe, secure, and fully operational.

The 058420 screw features a standard 1/4-20 UNC thread (listed as .250-20) and a length of 0.56 inches. Its defining feature is the knurled thumb head, which is designed specifically for hand-tightening. This design eliminates the need for screwdrivers or wrenches, making it an excellent choice for access panels, covers, or adjustable components that require frequent removal or repositioning. The textured knurling provides a non-slip grip, allowing operators to tighten or loosen the screw securely even while wearing work gloves.

Constructed from high-quality plated steel, this screw offers essential durability and resistance to rust and corrosion. Welding environments are often exposed to humidity, fumes, and temperature fluctuations that can degrade inferior hardware. The plating on this Miller screw acts as a protective barrier, extending the lifespan of the fastener and preventing it from seizing in the threads over time. Whether you are performing routine maintenance or a quick repair on the shop floor, relying on OEM plated steel hardware ensures your machine holds up to the rigors of daily industrial use.

This product is sold as a single unit, allowing you to purchase exactly the quantity needed for your specific repair. It is compatible with a variety of Miller power sources and wire feeders where tool-free access is prioritized. By choosing the Miller 058420, you are investing in the longevity of your equipment and minimizing downtime caused by ill-fitting generic hardware.
