Professional Applications & Engineering Value
This specialized left-hand tube end weld nut addresses critical safety and reliability challenges in hydraulic, pneumatic, and process systems where reverse-rotation scenarios occur. The 4130 Alloy Steel construction delivers exceptional strength-to-weight ratio, resisting deformation under high torque conditions common in industrial equipment. The UNF fine threading (5/16"-24) combined with Class 2B fit ensures leak-free connections in fluid transfer applications while the left-hand thread direction provides failsafe protection in rotating assemblies. Engineered specifically for 3/4" OD tubing with 0.058" wall thickness, this weld nut eliminates compatibility issues in critical tube fitting applications across aerospace, automotive, and heavy machinery sectors.
Specification Summary & Compliance
This tube end weld nut features 5/16"-24 UNF left-hand fine threading with Class 2B thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy. The partially threaded design provides 3/4" engagement length with 1" overall height. Manufactured from 4130 Alloy Steel for optimal mechanical properties. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial components.
