• Superior tube system integration designed specifically for 1" OD tubes with 0.083" wall thickness, ensuring perfect fit and performance.
• Full threading for maximum grip across the entire 1-1/2" length, distributing load evenly and enhancing joint integrity.
• Fine UNF thread spacing offering better adjustment control and superior resistance to vibrational loosening compared to coarse threads.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries worldwide.

Professional Applications & Engineering Value

This 5/8"-18 UNF left-hand thread tube end weld nut solves critical engineering challenges in hydraulic systems, pneumatic assemblies, and structural frameworks where reverse threading prevents unintended disassembly. The 4130 alloy steel construction delivers exceptional tensile strength and fatigue resistance, making it suitable for high-stress environments like aerospace, automotive, and heavy machinery. The Class 2B thread fit provides precise tolerance control, eliminating play and ensuring leak-proof connections in tube systems. With full threading and fine UNF spacing, it maintains consistent pressure distribution across the entire 1-1/2" thread length, significantly reducing the risk of stress concentration points. Designed specifically for 1" OD tubes with 0.083" wall thickness, this weld nut eliminates compatibility issues while the left-hand thread direction offers specialized solutions for counter-rotational mechanisms where standard threading would be insufficient.

Specification Summary & Compliance

This tube end weld nut features 5/8"-18 UNF left-hand fine threading with Class 2B fit precision tolerances, ensuring consistent thread engagement and dimensional accuracy. Manufactured from 4130 alloy steel with full threading across the 1-1/2" length, it meets inch system measurement standards. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to international environmental and safety standards for industrial components.
