Miller OEM Replacement Screw, 4-40 x 0.31 Pan Head Phillips (Pack of 4)

Keep Your Miller Welder Running Tight

There is nothing more frustrating than pausing a job because of a missing or stripped screw on your welding machine. Whether you are performing routine maintenance, replacing a cooling fan, or swapping out a control board, having the right hardware is essential to getting your machine back up and running safely. The Miller 251257 Screw is the exact replacement part you need to secure panels, components, and covers on your trusted Miller equipment. Don't settle for hardware store guesswork that might strip your threads or rust out in a month; stick with the genuine article.

This pack contains four (4) high-quality machine screws, giving you spares for your toolbox. Each screw is sized at 4-40 thread by 0.31 inches long, a specific size used frequently across the Miller product line. The Pan Head design sits flush against the surface, providing a clean look and a secure hold without sharp edges sticking out. Because they are made from plated steel, these screws are built to handle the tough environment of a welding shop. They resist rust and corrosion, ensuring that the next time you need to open up your machine, the screw will turn freely rather than being seized by oxidation.

Installation is straightforward using a standard Phillips head screwdriver. The Phillips drive is designed to cam out before you over-torque the screw, protecting the threads on your expensive machine from damage. These screws are perfect for securing sheet metal skins, mounting internal electrical components, or fastening access panels. When you use genuine Miller parts, you are preserving the resale value and reliability of your welder.

Small parts play a big role in safety and performance. A loose panel can cause rattling, noise, or even expose internal live circuits. By replacing missing hardware immediately with the Miller 251257, you ensure your workspace remains safe and your equipment professional. Verify your machine's parts manual to confirm fitment, but if you need a 4-40 x .31 Pan Head Phillips screw, this is the authentic Miller part for the job.
