Professional Applications & Engineering Value

This left-hand tube end weld nut addresses critical challenges in hydraulic systems, pneumatic assemblies, and structural tubing where reverse-thread applications prevent accidental disassembly. The 4130 alloy steel construction delivers exceptional tensile strength and fatigue resistance in high-vibration environments, while the UNF fine threading maintains secure connections under dynamic loads. Engineered specifically for 7/8" OD tubing with 0.065" wall thickness, this partially threaded design allows for precise weld positioning without compromising thread integrity. The Class 2B thread fit ensures consistent engagement in industrial tube fittings where reliability is paramount for system safety and performance.

Specification Summary & Compliance

This weld nut features 3/8"-24 UNF left-hand fine threading with Class 2B thread fit and 1" thread length. Manufactured to inch system standards with precise dimensional tolerances, the component is RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting the latest environmental regulations for industrial fasteners. The specification ensures compatibility with 7/8" tube OD and 0.065" wall thickness applications.
