079240 - Miller 079240 Screw, 3/8-16 x 1.75 Hex Head Plated Steel

Fix Your Welder with the Right Parts

Keep your Miller welder running tight and right with the Miller 079240 Screw. This is a genuine replacement bolt used in various Miller power sources and equipment. When you are deep in a repair job, the last thing you want is to struggle with mismatched hardware or stripped threads. This 3/8-16 x 1.75 inch hex head screw is the exact part specified by Miller engineers, ensuring that your machine goes back together exactly the way it was built. Don't settle for generic bin-parts that might snap or rust; stick with OEM quality for your expensive equipment.

Heavy-Duty Construction

Welding machines take a beating. Between the vibration of the shop, transport in trucks, and the heat of operation, every bolt counts. The Miller 079240 is made from plated steel, giving it the strength to hold heavy components in place and the durability to resist rust. The full thread design means this bolt provides grip all the way down, which is perfect for applications requiring a wide range of adjustment or maximum holding power in a threaded casting. The standard hex head allows you to crank it down securely using your standard 9/16" wrench or socket.

Why Fitment Matters

Have you ever tried to force a metric bolt into a standard hole? It’s a nightmare that ruins parts. This screw features a standard American .375-16 UNC thread. By ordering the specific Miller part number 079240, you eliminate the guessing game at the hardware store. You know the length (1.75 inches) will be perfect—not too short to grab, and not so long that it bottoms out or interferes with internal wiring. Proper fasteners are cheap insurance against future breakdowns caused by loose parts rattling around inside your power source.

Maintenance Tips

If you are opening up your welder to replace a fan, a board, or just to blow out the dust, take a minute to check your hardware. Vibrations from cooling fans and transformers can loosen screws over time. If you find a missing or stripped bolt, replace it immediately. This screw is a common size used for chassis assembly and internal mounting. Keeping a few of these 079240 screws in your spare parts bin is a smart move for any shop that relies on Miller equipment to pay the bills. Get your machine fixed up and get back to burning wire.
