S-94640A206 3/8"-24 Weld Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance with left-hand UNF fine threading that prevents loosening in high-torque applications
• Exceptional strength-to-weight ratio from 4130 alloy steel construction for demanding industrial environments
• Precise tube system integration with 1" tube OD compatibility and 0.058" wall thickness specification
• Reliable thread engagement through Class 2B thread fit ensuring consistent performance in welded assemblies
• Optimized welding efficiency with partial threading design that simplifies installation while maintaining structural integrity
• Extended service life with 1½" height providing enhanced stability and load distribution
• Global compliance assurance meeting RoHS 3 and REACH regulations for international industrial applications

Professional Applications & Engineering Value

This 4130 alloy steel tube end weld nut delivers critical performance in demanding fluid transfer and structural systems where reverse-thread security is paramount. The left-hand 3/8"-24 UNF fine threading provides counter-rotational stability in rotating machinery, hydraulic systems, and aerospace applications where standard right-hand threads would naturally loosen. Engineered specifically for 1" OD tubing with 0.058" wall thickness, this partially threaded weld nut ensures precise alignment during welding operations while the Class 2B thread fit maintains consistent engagement in high-vibration environments. The robust construction addresses common failure points in tube-end connections, offering engineers a reliable solution for permanent, high-strength fastening in critical industrial assemblies.

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, providing precise dimensional accuracy for reliable assembly. The 1" thread length and 1½" overall height ensure optimal engagement and structural support. Manufacturing compliance includes full conformance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material traceability for global industrial applications.
