005464 - Miller 1/4-20 x 0.37 Inch Oval Point Set Screw with Nylok

Technical Overview of the Miller 005464 Set Screw

The Miller 005464 is a precision-engineered set screw designed specifically for use within Miller welding power sources and auxiliary equipment. As a genuine OEM component, it adheres strictly to the dimensional and material specifications required to maintain the structural integrity and operational reliability of your machinery. This fastener features a 1/4-20 UNC thread pitch, a standard coarse thread widely used in industrial applications for its robust holding power and ease of assembly.

Measuring 0.37 inches (approximately 3/8 inch) in length, this set screw is manufactured from plain steel (STL PLN), offering the necessary tensile strength for internal machine assembly where corrosion resistance is managed by the enclosure environment. A defining technical feature of this SKU is the "OVL PT" or Oval Point design. Unlike cup point screws which cut into the mating shaft or surface to provide grip, an oval point screw has a rounded tip. This design is critical in applications where the screw bears against a shaft that may need frequent adjustment or where minimizing surface deformation on the mating part is required. It provides excellent holding power when seated into a groove or against a flat surface without damaging the substrate.

Furthermore, the inclusion of "NYLOK" technology is a significant specification. The Nylok patch is a pre-applied nylon element fused to the threads of the screw. When the screw is installed, the nylon is compressed, creating a counter-force that pushes the screw threads against the mating threads. This metal-to-metal contact creates friction that prevents the fastener from loosening due to the high-frequency vibrations often generated by welding transformers, cooling fans, and engine drives. For maintenance personnel and technicians, utilizing this specific part ensures that repairs hold up under the rigorous duty cycles of industrial welding equipment.

Installation typically requires a hex key (Allen wrench), allowing for high torque application relative to the screw's size. The socket head design ensures the tool does not slip, protecting surrounding sensitive electronic components during maintenance procedures.
