S-94640A303 3/8"-24 Weld Nuts

Key Features & Benefits at a Glance

• Enhanced torque resistance with left-hand threading for secure fastening in rotating applications where standard right-hand threads may loosen
• Superior strength and durability from 4130 Alloy Steel construction, ideal for high-stress industrial environments
• Precise thread engagement with Class 2B fit and UNF fine threading, ensuring reliable, vibration-resistant connections
• Optimized tube compatibility designed specifically for 1" OD tubes with 0.095" wall thickness, reducing installation errors
• Partial threading design allows for flexible positioning and easier alignment during welding operations
• Environmental compliance with RoHS 3 and REACH standards, meeting global regulatory requirements for industrial use
• Corrosion-resistant performance from alloy steel material, extending service life in demanding conditions

Professional Applications & Engineering Value

This 3/8"-24 UNF left-hand tube end weld nut addresses critical challenges in hydraulic, pneumatic, and fluid transfer systems where reverse rotation prevention is essential. The 4130 Alloy Steel construction provides exceptional tensile strength and fatigue resistance, while the Class 2B thread fit maintains precise tolerances under vibration and thermal cycling. The left-hand UNF fine threading specifically counters unintentional loosening in clockwise-rotating machinery, making it invaluable for industrial equipment, automotive assemblies, and aerospace applications. Its partial threading design facilitates perfect alignment with 1" OD tubing systems, streamlining installation while maintaining structural integrity under pressure and mechanical stress.

Specification Summary & Compliance

This tube end weld nut features 3/8"-24 UNF left-hand fine threading with Class 2B thread fit per UNF standards, ensuring precise dimensional accuracy. The 1" thread length and 1-1/2" height provide optimal engagement for tubing applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and restricted substance compliance for global industrial distribution.
