S-94640A420 3/8"-24 Weld Nuts

Key Features & Benefits at a Glance

• Superior tube connection integrity with precise 1" tube OD and 0.083" wall thickness compatibility for leak-free performance
• Enhanced thread engagement reliability through Class 2B thread fit, ensuring consistent assembly and vibration resistance
• Exceptional strength-to-weight ratio from 4130 Alloy Steel construction, ideal for high-stress industrial environments
• Optimized fastening efficiency with 3/8"-24 UNF fine threading and right-hand direction for standard tool compatibility
• Reduced installation complexity via partially threaded design, allowing precise positioning before welding
• Long-term environmental compliance meeting RoHS 3 and REACH standards for global industrial applications
• Reliable weld joint performance through specialized tube end design that maintains structural integrity post-welding

Professional Applications & Engineering Value

This tube end weld nut addresses critical challenges in fluid systems and structural frameworks where 4130 Alloy Steel provides optimal strength for pressurized applications. The UNF fine threading (3/8"-24) with Class 2B precision prevents cross-threading during assembly while maintaining seal integrity in hydraulic, pneumatic, and fuel line systems. Its partially threaded configuration allows for exact alignment on 1" OD tubing before permanent welding, eliminating misalignment issues that compromise system safety. The combination of right-hand threading and specified wall thickness compatibility (0.083") ensures uniform stress distribution, making it indispensable for aerospace, automotive, and heavy machinery applications requiring reliable tube termination solutions.

Specification Summary & Compliance

Manufactured to UNF thread standards with Class 2B thread fit tolerances for consistent engagement. The partially threaded design provides 1" of usable thread length with fine thread spacing. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring material safety and environmental responsibility. Engineered specifically for 1" tube OD applications with 0.083" wall thickness requirements in inch measurement systems.
