The Miller 261463 is a specialized industrial fastener designed to meet the rigorous engineering standards of Miller Electric welding equipment. As a genuine OEM component, this screw is manufactured to precise tolerances to ensure seamless integration with existing machine assemblies. The fastener features a 5/16-18 UNC thread profile, a standard coarse thread widely used in heavy machinery for its resistance to cross-threading and ability to hold tight under vibration. With a total length of 4.50 inches, this screw is utilized in applications requiring significant reach or clamping thickness within the welder's chassis or internal components.
Material composition is a critical factor in the performance of this component. The screw is fabricated from Grade 5 steel, a medium-strength carbon steel that has been quenched and tempered. Grade 5 fasteners typically offer a minimum tensile strength of 120,000 PSI, making them significantly stronger than standard Grade 2 hardware often found in general hardware stores. This added strength is essential for maintaining the structural rigidity of heavy welding power sources and wire feeders, which are often subjected to mechanical stress and movement.
The "Hex Head" design allows for the application of high torque values using standard socket or open-end wrenches, ensuring a secure fit that resists loosening over time. Furthermore, the "PLD" (Plated) specification indicates a surface treatment—likely zinc or a similar protective coating—applied to the plain steel substrate. This plating provides a barrier against oxidation and corrosion, a necessary feature for equipment that may be used in humid or variable industrial environments. The "FULL" designation confirms that the shank is fully threaded, offering maximum versatility for grip length and adjustment.
