S-94640A130 5/16"-24 Weld Nuts

Key Features & Benefits at a Glance

• Superior tube connection integrity with precise 5/8" tube OD compatibility and 0.058" wall thickness support for leak-proof industrial assemblies
• Enhanced thread engagement reliability through Class 2B thread fit ensuring consistent fastening performance in high-vibration environments
• Exceptional strength-to-weight ratio from 4130 alloy steel construction providing robust load-bearing capacity while resisting deformation
• Optimized fine-thread performance with 5/16"-24 UNF right-hand threading delivering superior resistance to loosening under dynamic loads
• Simplified welding installation through partially threaded design allowing secure tube end attachment without compromising thread integrity
• Long-term corrosion resistance with material properties that maintain structural stability in demanding industrial atmospheres
• Global compliance assurance meeting RoHS 3 and REACH environmental standards for international project specifications

Professional Applications & Engineering Value

This tube end weld nut delivers critical performance in hydraulic, pneumatic, and fluid transfer systems where 4130 alloy steel provides the necessary strength for pressure-containing applications. The partially threaded configuration allows for secure welding to tube ends while preserving the full 3/4" thread length for proper fastener engagement. Engineered with UNF fine threading (5/16"-24), this component maintains sealing integrity in systems subject to vibration and thermal cycling. The Class 2B thread fit ensures consistent mating with male threads, preventing fluid leakage in critical 5/8" tube OD applications across aerospace, automotive, and heavy equipment industries where reliability cannot be compromised.
