275568 - Miller 275568 Hex Washer Head Screw .250-14 x .75 (Pack of 10)

Genuine Miller Replacement Hardware

The Miller 275568 Screw is a genuine OEM replacement component designed specifically for Miller welding equipment. When maintaining high-performance machinery, using authentic parts is crucial to ensure the longevity and reliability of your equipment. This specific fastener is a .250-14 x .75 Hex Washer Head screw featuring a Type-B thread profile. It is commonly used in the assembly of chassis panels, internal components, and structural elements of various Miller power sources and wire feeders. By choosing genuine Miller parts, you ensure that the dimensional tolerances and material strength match the original engineering specifications of your machine.

Durable Construction and Design

Engineered for industrial environments, this screw features a zinc-plated finish. Zinc plating is essential for welding equipment that may be exposed to varying shop conditions, as it provides a robust layer of protection against oxidation and corrosion. The Hex Washer Head (HEXWHD) design is particularly beneficial in assembly applications; the integrated washer distributes pressure over a wider area than a standard hex head, reducing the risk of crushing sheet metal or damaging painted surfaces. Additionally, the hex drive allows for positive torque transfer, minimizing the chance of driver slippage (cam-out) during installation or removal.

Type-B Thread Specification

The Type-B thread designation indicates that this is a spaced-thread tapping screw with a blunt point and incomplete tapered threads at the pilot end. These screws are designed for use in heavier gauge sheet metal, non-ferrous castings, or plastics where a sharp point is not required or desirable. The .250-14 thread size (1/4 inch diameter with 14 threads per inch) is a standard coarse thread that provides excellent holding power. This pack contains 10 screws, making it an excellent addition to any maintenance technician's spare parts inventory, ensuring you have the right hardware on hand when performing routine service or repairs.
