Professional Applications & Engineering Value
This specialized tube end weld nut addresses critical challenges in hydraulic systems, pneumatic assemblies, and industrial tubing networks where left-hand threading prevents accidental disengagement in rotating machinery. The 4130 alloy steel composition provides exceptional tensile strength and fatigue resistance, crucial for high-pressure applications and vibration-prone environments. Engineered with UNF fine threading and Class 2B thread fit, this nut ensures precise alignment and secure fastening in tubing systems requiring 1" OD compatibility. The partially threaded design facilitates proper welding while maintaining thread integrity, making it ideal for permanent installations in aerospace, automotive, and heavy equipment manufacturing where reliability is paramount.
Specification Summary & Compliance
This weld nut features 7/16"-20 UNF left-hand fine threading with Class 2B thread fit tolerance, ensuring precision engagement in industrial applications. The manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, confirming regulatory adherence for global industrial use. Designed specifically for 1" OD tubing with 0.065" wall thickness, the nut maintains dimensional accuracy with 1" thread length and 1-1/2" overall height for consistent performance in tube end connection systems.
