Professional Applications & Engineering Value
This 4130 Alloy Steel tube end weld nut delivers exceptional engineering value in hydraulic systems, pneumatic assemblies, and structural tubing applications where reliable threaded connections are critical. The partially threaded UNF fine thread design prevents cross-threading during installation while maintaining consistent clamping force in high-pressure environments. Engineered specifically for 1-1/8" OD tubes with 0.095" wall thickness, this weld nut provides superior weld integrity and distributes stress evenly across the joint. The right-hand thread direction ensures compatibility with standard industrial equipment, making it ideal for aerospace, automotive, and heavy machinery applications where vibration resistance and long-term reliability are paramount.
Specification Summary & Compliance
This precision tube end weld nut features 1/2"-20 UNF fine threading with Class 2B thread fit tolerance for optimal engagement, manufactured to exacting industrial standards. The component maintains dimensional accuracy with 1-1/4" thread length and 1-1/2" overall height. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures suitability for global markets and environmentally conscious manufacturing processes.
