S-94640A450 7/16"-20 Weld Nuts

Key Features & Benefits at a Glance

• Superior tube connection integrity with precise compatibility for 1" OD tubes and 0.095" wall thickness, ensuring leak-proof performance in fluid systems
• Enhanced fatigue resistance from 4130 Alloy Steel construction, providing reliable strength in high-vibration industrial environments
• Optimized thread engagement with Class 2B fit and 1" thread length for secure fastening while minimizing cross-threading risks
• Fine UNF threading (7/16"-20) delivers higher torque accuracy and better load distribution compared to coarse threads
• Right-hand partial threading enables controlled installation depth and prevents over-tightening in confined spaces
• Full regulatory compliance with RoHS 3 and REACH standards, ensuring environmental safety and global market acceptance
• 1-1/2" height profile provides substantial welding surface area for permanent, high-strength tube end attachments

Professional Applications & Engineering Value

This 4130 Alloy Steel tube end weld nut solves critical challenges in hydraulic, pneumatic, and structural tubing systems where vibration resistance and pressure integrity are paramount. The partially threaded UNF design with Class 2B precision ensures consistent engagement without compromising the tube's structural integrity during welding operations. Engineers specify this weld nut for 1" tube OD applications particularly in heavy machinery, automotive frames, and industrial equipment where fine threading provides superior clamping force distribution. The right-hand threading accommodates standard installation tools while the specific 0.095" wall thickness compatibility prevents deformation during final assembly, making it ideal for high-stress junction points that demand both welding reliability and threaded connection precision.

Specification Summary & Compliance

This tube end weld nut maintains Class 2B thread fit tolerances per UNF standards with 7/16"-20 fine threading and 1" thread length. Manufacturing conforms to industry standards for 4130 Alloy Steel weld nuts with partial threading configuration. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety requirements for industrial components.
