- Optimized welding stability through partial threading design that maintains structural integrity during welding operations
- Perfect compatibility with 5/8" OD tubing and 0.058" wall thickness for leak-proof fluid system connections
- Full regulatory compliance with RoHS 3 and REACH standards for safe use in global industrial markets
- Enhanced installation efficiency with 1" height providing ample surface area for consistent weld placement
Professional Applications & Engineering Value
This left-hand thread tube end weld nut solves critical challenges in hydraulic, pneumatic, and fluid transfer systems where reverse rotation prevention is essential. The 4130 alloy steel construction delivers exceptional tensile strength and heat resistance during welding operations, while the UNF fine threading maintains sealing integrity under high-vibration conditions. Engineers specify this partially threaded design for tubing applications requiring precise alignment with 5/8" OD and 0.058" wall thickness, ensuring reliable performance in aerospace, automotive, and heavy equipment industries where Class 2B thread fit guarantees consistent mating with corresponding components.
Specification Summary & Compliance
This tube end weld nut features 5/16"-24 UNF fine threading with Class 2B thread fit tolerance, 3/4" thread length, and 1" overall height. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. The nut is engineered for 5/8" OD tubing with 0.058" wall thickness applications, providing reliable performance in industrial fastening systems requiring left-hand thread security.
