Miller 195701 1/2-13 Zinc Plated Hex Nut (3-Pack)

Technical Specifications: Miller 195701 Nut

The Miller 195701 is a specific hardware component utilized across various Miller Electric welding power sources and auxiliary equipment. This product is supplied as a package of 3, facilitating multiple replacements or small-batch inventory stocking for maintenance departments. The nut is a standard hex configuration designed for structural and component fastening within the machine assembly.

Dimensional Data

This fastener is machined with a 1/2-13 UNC thread (Unified National Coarse). The 0.500-inch nominal diameter combined with 13 threads per inch is a common specification for load-bearing applications in industrial machinery. The nut features a 0.750-inch (3/4") hex width across flats, compatible with standard SAE wrenches and sockets. The height (thickness) of the nut is 0.44 inches, providing sufficient thread engagement to meet proof load requirements for Grade 2 or Grade 5 equivalent steel assemblies.

Material and Finish

Material composition is a critical factor in welding equipment hardware. The 195701 is fabricated from steel and treated with a zinc electroplating followed by a clear chromate conversion coating. This finish serves two primary technical functions:

• Corrosion Protection: The zinc acts as a sacrificial anode, protecting the underlying steel from oxidation. The clear chromate passivate further delays the onset of white corrosion (zinc oxide), extending the service life of the part in non-climate-controlled environments.
• Lubricity: Zinc plating provides a consistent friction coefficient, ensuring that torque values applied during assembly result in predictable clamping force (preload).

Application Notes

Technicians should verify the part number 195701 against the specific machine's parts breakdown or service manual. Due to the conductive nature of metallic fasteners, ensure this nut is used in the correct location as specified by the manufacturer to maintain proper electrical grounding or isolation as intended by the equipment design.
