274168 - Miller 274168 Coupling Nut 5/16-18 Steel

Miller 274168 Steel Coupling Nut (5/16-18)

The Miller 274168 is a specialized Coupling Nut designed for use in Miller Electric welding power sources and accessories. When repairing or refurbishing industrial equipment, precision is key. This OEM component ensures that threads align perfectly and that the structural integrity of the assembly is maintained. It is identified technically as a NUT, 312-18 .50HEX 1.12H STL PLD CLR COUPLING, indicating its precise dimensions and material composition.

Technical Specifications:

This coupling nut features a .312-18 thread, which translates to the standard 5/16-18 coarse thread size. The body of the nut is machined into a 0.50-inch (1/2") hex shape, providing a solid grip for tools during torque application. With a total height of 1.12 inches, it provides ample length for connecting male threaded ends or acting as a standoff spacer in electronic or mechanical assemblies within the welder. The construction is solid steel (STL), ensuring high tensile strength, and it is treated with a clear plating (PLD CLR) to resist oxidation.

Application and Fitment:

Coupling nuts are frequently used in wire drive assemblies, chassis construction, and internal component mounting. Because Miller equipment is built to last, the hardware used inside must be equally robust. This part is a direct replacement for the original hardware found in your machine. To ensure this is the correct part for your specific model, please verify the part number against the breakdown in your owner's manual or check your machine's serial number. Using genuine Miller parts helps maintain the warranty status and safety of your welding setup.
