S-94640A230 7/16"-20 Weld Nuts

Key Features & Benefits at a Glance

• Enhanced Durability & Strength: Crafted from 4130 Alloy Steel for superior resistance to stress and wear in demanding industrial environments.
• Precision Thread Fit: Class 2B thread fit ensures smooth, reliable engagement with mating components, reducing the risk of cross-threading and assembly errors.
• Optimized for Tube Systems: Specifically designed for 3/4" OD tubes with a 0.065" wall thickness, providing a secure and leak-resistant connection.
• Secure Fastening with Fine Threads: 7/16"-20 UNF fine threading offers a higher number of threads per inch, resulting in better vibration resistance and clamping force.
• Efficient Partial Threading: The 1 1/8" partially threaded design allows for easier starting and alignment during the welding process, speeding up installation.
• Right-Hand Thread Convenience: Standard right-hand thread direction ensures compatibility with common tools and simplifies the assembly procedure.
• Environmental & Regulatory Compliance: Meets RoHS 3 and REACH standards, ensuring the nut is free from hazardous substances for safe use in global markets.

Professional Applications & Engineering Value

This Tube End Weld Nut is engineered to address critical challenges in fluid and structural systems where reliable, leak-proof connections are paramount. The 4130 Alloy Steel construction provides excellent tensile strength and fatigue resistance, making it ideal for high-pressure and high-vibration applications such as hydraulic lines, pneumatic systems, and automotive frameworks. The UNF fine threading and Class 2B thread fit ensure precise, repeatable assembly, minimizing the risk of thread stripping and enhancing the longevity of the connection. By specifying this nut for 3/4" OD tubes, engineers can achieve consistent performance in industrial weld nut applications, from heavy machinery to aerospace assemblies, where material integrity and compliance with international standards are non-negotiable.
