61340127 - ESAB 3/8-16 x 2 Inch Zinc Plated Steel Replacement Screw

Technical Overview of the ESAB 61340127 Replacement Screw

The ESAB 61340127 is a specialized replacement screw designed to meet the rigorous mechanical standards of industrial welding equipment. Identified by the specification string SCR 10005 STLZPC 0.375-16X2.00, this fastener is engineered from high-grade steel (STL), ensuring the necessary tensile strength to secure critical components within heavy-duty machinery. The fastener features a 0.375-inch (3/8-inch) nominal diameter with a coarse thread pitch of 16 threads per inch (UNC), a standard configuration for load-bearing applications in North American industrial equipment.

A key technical feature of this component is its Zinc Plated Clear (ZPC) finish. In industrial environments, equipment is frequently exposed to humidity, thermal fluctuations, and atmospheric contaminants. The zinc plating acts as a sacrificial anode, protecting the underlying steel substrate from oxidation and corrosion. This extends the service life of the fastener and prevents seizing, which can complicate future maintenance or disassembly tasks. The 2.00-inch length is precisely calibrated to engage the mating threads fully, ensuring maximum clamping force without bottoming out or protruding excessively, which could interfere with other internal components.

Maintenance professionals and MRO specialists understand that substituting OEM hardware with generic bin-stock fasteners can lead to mismatched tolerances or inadequate material grades. The ESAB 61340127 ensures that the replacement part matches the original engineering specifications of the welding power source or wire feeder. Whether used for securing chassis panels, internal transformers, or structural frames, this screw maintains the structural integrity of the unit. Its coarse thread profile is particularly well-suited for materials like steel and cast iron, providing robust resistance to stripping during installation and loosening under vibration.

When integrating this part into a repair workflow, verify the thread condition of the receiving hole. The 3/8-16 UNC thread profile requires a clean mating surface to achieve the correct torque specifications. Using genuine ESAB parts like the 61340127 guarantees that the hardness and shear strength of the screw are appropriate for the specific load it bears within the ESAB assembly, maintaining the safety and reliability of the equipment.
