Professional Applications & Engineering Value
This tube end weld nut delivers critical engineering solutions for industrial fluid systems and mechanical assemblies requiring left-hand thread security. The 4130 alloy steel construction provides exceptional tensile strength and durability in high-stress applications, while the UNF fine threading offers superior resistance to vibrational loosening in rotating equipment. Engineered specifically for 1" OD tubing with 0.083" wall thickness, this partially threaded design maintains tube integrity during welding operations, preventing distortion and ensuring leak-proof connections. Ideal for aerospace, hydraulic systems, and heavy machinery, this component addresses common failure points in tube-end connections through precision manufacturing and material excellence.
Specification Summary & Compliance
This tube end weld nut features 1/2"-20 UNF left-hand fine threading with Class 2B thread fit for precise tolerance control. The partially threaded design incorporates 1-1/4" thread length and 1-1/2" overall height. Manufactured to exacting standards for compatibility with 1" tube OD and 0.083" wall thickness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
