S-94640A104 7/16"-20 Weld Nuts

Key Features & Benefits at a Glance

• Exceptional strength and fatigue resistance from 4130 Alloy Steel, ideal for high-stress industrial environments.
• Precise Class 2B thread fit ensures smooth assembly and reliable, vibration-resistant connections in demanding applications.
• Left-hand threading provides secure fastening in systems where right-hand rotation could cause loosening, enhancing operational safety.
• Fully threaded design allows for maximum engagement and adjustability on 5/8" OD tubes with 0.058" wall thickness.
• Fine UNF thread spacing delivers superior holding power and finer adjustment control compared to coarse threads.
• RoHS 3 and REACH compliance guarantees environmental safety and regulatory adherence for global supply chains.
• Optimized 1" height offers ample thread contact area for robust, long-lasting welded joints in tube end systems.

Professional Applications & Engineering Value

This 7/16"-20 UNF left hand thread weld nut is engineered to address critical challenges in industrial and mechanical assemblies, particularly where reverse-thread security is essential. Crafted from 4130 Alloy Steel, it provides superior tensile strength and corrosion resistance, reducing failure risks in high-vibration settings like automotive, aerospace, and heavy machinery. The fully threaded and fine thread spacing design ensures maximum load distribution on 5/8" OD tubes, preventing stripping and maintaining integrity under dynamic stresses. Its tube end configuration simplifies welding processes, offering a reliable solution for fluid systems, structural frames, and custom fabrications that demand precise, Class 2B fit tolerances and left-hand thread functionality to counter rotational forces.
