S-94640A250 3/8"-24 Weld Nuts

Key Features & Benefits at a Glance

• Superior tube connection integrity with precise 7/8" tube OD compatibility for leak-resistant industrial fluid systems
• Enhanced thread engagement reliability through Class 2B thread fit precision, reducing cross-threading risks during assembly
• Exceptional mechanical strength from 4130 alloy steel construction, maintaining structural integrity under high vibration and load conditions
• Optimized partial threading design (1" thread length) allows for precise positioning while minimizing material usage
• Fine UNF thread spacing (24 TPI) provides superior vibration resistance compared to coarse threads in dynamic applications
• Right-hand threading standardization ensures compatibility with common industrial equipment and simplifies installation procedures
• Full regulatory compliance with RoHS 3 and REACH standards, meeting global environmental and safety requirements

Professional Applications & Engineering Value

This tube end weld nut delivers critical performance in demanding fluid transfer and structural systems where 4130 alloy steel provides the necessary strength-to-weight ratio for aerospace, hydraulic, and high-pressure applications. The partially threaded design with 1" thread length allows for precise weld positioning while the UNF fine threading (3/8"-24) maintains superior vibration resistance in dynamic environments. Engineered specifically for 7/8" tube OD compatibility with 0.065" wall thickness, this nut solves common challenges of tube fitting integrity, preventing leaks and connection failures in industrial fluid systems. The Class 2B thread fit ensures smooth assembly while maintaining the tight tolerances required for critical connections in manufacturing and equipment applications.
