61330086 - ESAB 1/4-20 x 0.38 Zinc Plated Steel Screw

Technical Overview of the ESAB 61330086 Replacement Screw

The ESAB 61330086 is a precision-manufactured machine screw designed to meet the specific assembly requirements of ESAB welding equipment and industrial machinery. Identified by the specification string SCR 13011 STLZPC 0.250-20X0.38, this component features a standard 0.250-inch diameter with a thread density of 20 threads per inch (1/4-20 UNC), a common configuration in North American industrial design. The shaft length is calibrated to 0.38 inches (approximately 3/8 inch), making it suitable for fastening sheet metal panels, securing internal components, or mounting accessories where thread depth is limited.

Material composition is a critical aspect of this fastener. It is constructed from steel, providing the necessary tensile strength to hold components securely under the vibration and thermal cycling often present in welding environments. To mitigate environmental degradation, the steel is treated with a zinc plating (STLZPC). This sacrificial coating prevents oxidation and rust formation, ensuring that the fastener remains removable for future maintenance and maintains structural integrity over time. As an OEM part, it guarantees dimensional accuracy, eliminating the risks associated with generic hardware that may have slight tolerance deviations.

Maintenance professionals and equipment technicians utilize this specific SKU to restore factory specifications during repair or overhaul procedures. Using the correct fastener is essential for maintaining the grounding continuity, mechanical stability, and safety of welding power sources and wire feeders.
