094724 - Miller 10-16 x 0.75 Hex Washer Head Sheet Metal Screw

Technical Specifications and Application

The Miller 094724 is a specialized 10-16 x 0.75 Hex Washer Head Sheet Metal Screw intended for use in the assembly and repair of Miller welding equipment. For technicians and welders performing maintenance on their power sources, wire feeders, or cooling systems, identifying and using the correct fastener is critical for maintaining the NEMA rating and mechanical stability of the unit. This screw is defined by its specific geometry: a #10 diameter with 16 threads per inch, a 3/4-inch length, and a Type AB point.

The Type AB point is a thread-forming screw typically used in thin metal. It features a spaced thread similar to a Type A but with a finer pitch, allowing for greater holding power in sheet metal applications. This is particularly relevant for welding machines where vibration from transformers or fans can loosen inferior fasteners over time. The "HexwHD" designation indicates a Hex Washer Head. This integrated washer face provides a larger surface area under the head, which eliminates the need for a separate washer and increases the pull-through resistance—a vital feature when securing the relatively thin gauge steel used in welder cases.

Material composition is Plated Steel. The plating (likely Zinc) serves as a sacrificial anode, preventing the steel core of the screw from rusting. In a welding environment, where fumes and temperature fluctuations are common, this protection ensures the screw remains removable for future service. The 0.41-inch head diameter is engineered to cover standard clearance holes in Miller chassis panels, ensuring a dust-tight seal when tightened. This prevents metallic dust from grinding operations from entering the machine housing.

When servicing Miller equipment, substituting this screw with a generic wood screw or a different thread pitch can ruin the receiving clip nut or the sheet metal hole itself, leading to rattling panels or compromised grounding. The Miller 094724 ensures that the electrical continuity (where applicable for grounding through the chassis) and mechanical rigidity of the unit are preserved. It is compatible with a wide range of Miller industrial machines. Always verify the part number in your specific machine's parts manual before installation to ensure this #10-16 x 0.75 screw is the correct fit for your specific location on the assembly.
