- Fine UNF thread spacing provides superior vibration resistance and load distribution in dynamic systems.
Professional Applications & Engineering Value
This 3/8"-24 UNF left-hand weld nut is engineered to address critical challenges in tube-based assemblies, such as hydraulic systems, pneumatic lines, and structural frameworks. Crafted from 4130 alloy steel, it offers high tensile strength and fatigue resistance, minimizing the risk of failure under cyclic loads. The partially threaded and tube end design simplifies alignment during welding, reducing assembly time and improving joint consistency. Its left-hand thread direction is essential for applications where standard right-hand threads may unintentionally loosen, providing added security in rotating machinery. With a Class 2B thread fit and UNF fine threading, it ensures precise, leak-free connections in high-pressure environments, making it a reliable choice for aerospace, automotive, and heavy equipment industries.
Specification Summary & Compliance
This weld nut features a 3/8"-24 UNF left-hand thread with Class 2B fit for consistent dimensional accuracy. It is manufactured from 4130 alloy steel and includes a 3/4" thread length and 1" height, designed for tubes with 5/8" OD and 0.058" wall thickness. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial use.
