197506 - Miller M14-1.5 x 30mm Hex Head Screw, Grade 8.8

High-Tensile M14-1.5 x 30mm Hex Screw for Miller Welders

Maintain the factory performance of your welding equipment with the Miller 197506 Screw, a high-quality replacement fastener engineered for durability and precision. This screw is identified by its specific dimensions: an M14 diameter paired with a 1.5mm fine thread pitch and a 30mm length. The distinction of a 1.5mm pitch is crucial; standard coarse M14 threads are typically 2.0mm. Attempting to force a coarse thread bolt into a fine thread hole can result in catastrophic damage to the internal threads of your machine's chassis or components. This genuine Miller part ensures a perfect, non-destructive fit every time.

Constructed from Grade 8.8 steel, this hex head screw delivers robust mechanical properties, including high yield strength and excellent toughness. Grade 8.8 is the standard for structural applications in mechanical engineering, providing the necessary clamping force to hold heavy components securely in place. In the context of welding machines, which may be subjected to transport vibration, thermal expansion, and contraction, the reliability of Grade 8.8 hardware is essential for long-term operation.

The hex head design is the industry standard for high-torque applications, allowing technicians to use sockets or wrenches to achieve the required torque specifications without the risk of cam-out associated with other drive types. The plain finish of this screw means it lacks a zinc or galvanized coating, which is often intentional in internal machine assemblies to ensure the tightest possible thread tolerance and electrical continuity where required. It is a direct replacement for the original hardware found in various Miller power sources and wire feeders.

At Welders Supply, we understand that downtime is costly. Having the right small parts on hand, like the Miller 197506, can be the difference between a quick fix and a prolonged delay. Always verify your machine's parts list or service manual to confirm fitment, as Miller uses various fasteners across their extensive product line. Invest in genuine OEM parts to ensure your equipment remains safe, secure, and ready to weld.
