• Optimized for 1 3/4" tube OD applications with 0.25" wall thickness compatibility, delivering reliable performance in tubular structures
• Full 2" threading length provides maximum thread engagement and load distribution across the entire nut height
• Comprehensive regulatory compliance with RoHS 3 and REACH standards ensures environmental responsibility and global market acceptance
• Weld-ready tube end design facilitates permanent installation while maintaining thread integrity during welding operations

Professional Applications & Engineering Value

This tube end weld nut delivers critical engineering solutions for applications requiring left-hand threading in tubular assemblies. The 4130 Alloy Steel construction provides exceptional strength-to-weight ratio, making it ideal for aerospace, automotive, and heavy equipment where vibration resistance is paramount. The UNF fine thread configuration offers superior clamping force distribution compared to coarse threads, while the left-hand direction provides fail-safe fastening in rotating systems where standard right-hand threads might loosen. The precise Class 2B thread fit ensures consistent performance in high-vibration environments, reducing maintenance intervals and preventing catastrophic assembly failures. Engineered specifically for 1 3/4" OD tubing with 0.25" wall thickness, this weld nut eliminates compatibility issues in hydraulic systems, structural frameworks, and mechanical linkages.

Specification Summary & Compliance

This tube end weld nut features 1"-14 UNF left-hand fine threading with Class 2B thread fit per unified thread standards, ensuring precise dimensional accuracy and reliable mating performance. The 2" thread length and 2" overall height provide optimal engagement characteristics. Manufacturing complies with industry standards for weld nuts in inch measurement systems. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting the latest environmental regulations for hazardous substance restrictions.
