602173 - Miller 602173 Set Screw #10-32 x 1/4 Cup Point Socket Head

Miller 602173 Set Screw: Precision Maintenance Part

Keep your welding operations running smoothly with the Miller 602173 Set Screw. This essential piece of hardware is a #10-32 x 0.25-inch socket head set screw, commonly referred to as a grub screw. It is designed to secure rotating or moving parts to a shaft, ensuring that the mechanical systems within your welder function correctly. Often overlooked, a missing or stripped set screw can lead to slipping drive rolls, loose control knobs, or malfunctioning internal gears, causing unnecessary downtime in your shop.

Technical Specifications

The Miller 602173 features a standard #10-32 thread, which is a fine thread pitch offering high strength and fine adjustment capabilities. The 1/4-inch length is compact, allowing it to sit flush or below the surface of the tapped hole for safety and clearance. The "Cup Point" geometry is engineered to cut a small ring into the mating part, providing a high coefficient of friction that resists loosening over time. This is particularly important in welding machines that may be moved frequently or subjected to mechanical vibration.

Installation and Tools

To install this set screw, you will need a compatible hex key (Allen wrench). The internal socket drive allows for precise torque application, ensuring the cup point engages firmly without stripping the head. Because it is made of durable steel, it resists deformation during tightening. We recommend checking the tightness of set screws periodically as part of your routine equipment maintenance schedule, especially on wire drive assemblies and fan components.

Why Choose OEM?

While it might be tempting to source fasteners from a general hardware bin, using the specific Miller 602173 ensures you have the correct hardness and point style intended by the engineers who designed your welder. Incorrect set screws can damage shafts or fail under load. By choosing genuine Miller components, you ensure that your repairs are permanent and your machine continues to operate at peak efficiency. This package contains one (1) set screw.
