Professional Applications & Engineering Value
This left-hand thread tube end weld nut addresses critical challenges in hydraulic, pneumatic, and structural tubing systems where standard right-hand threads may unscrew under vibration. Crafted from 4130 Alloy Steel, it offers superior tensile strength and corrosion resistance, reducing failure risks in heavy-duty applications like machinery, automotive, and aerospace frameworks. The UNF fine threading and Class 2B fit ensure tight seals and precise alignment, minimizing fluid leaks and assembly time. Its fully threaded design accommodates varying engagement depths, providing flexibility in welded assemblies for 1-1/8" OD tubes with 0.083" walls, delivering long-term reliability and performance.
Specification Summary & Compliance
This weld nut features a 5/8"-18 UNF left-hand thread with Class 2B thread fit for consistent dimensional accuracy, adhering to UNF fine thread standards. It measures 1-1/2" in height and is fully threaded for uniform load distribution. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for rigorous industrial use.
