Professional Applications & Engineering Value
This tube end weld nut solves critical challenges in hydraulic, pneumatic, and structural tubing systems where reverse rotation prevention is essential. The 4130 alloy steel construction delivers superior tensile strength and fatigue resistance, while the left-hand UNF fine threading provides anti-loosening properties in rotating machinery applications. The partial threading design allows for precise weld placement without damaging threads, maintaining Class 2B precision for consistent performance in aerospace, automotive, and heavy equipment industries. Engineered specifically for 7/8" OD tubing with 0.058" wall thickness, it ensures perfect sealing and mechanical stability in high-pressure environments.
Specification Summary & Compliance
This weld nut features 3/8"-24 UNF left-hand fine threading with Class 2B thread fit per UNF standards, ensuring precise dimensional accuracy and reliable performance. The 1" thread length and 1-3/8" height provide optimal engagement for tube end applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial fasteners worldwide.
