Professional Applications & Engineering Value
Engineered for high-stress tube and piping systems, this 7/8"-14 UNF tube end weld nut addresses critical challenges in fluid transport and structural frameworks. The 4130 alloy steel composition offers exceptional tensile strength and durability, resisting deformation under pressure fluctuations. Its fully threaded, right-hand design with Class 2B precision ensures uniform load distribution, preventing thread stripping in heavy-duty tube fittings. Ideal for hydraulic assemblies, industrial machinery, and aerospace applications, it maintains integrity in temperatures up to 800°F. The fine UNF threading enhances sealing capability, reducing maintenance downtime and leakage risks in 1-1/2" tube OD configurations.
Specification Summary & Compliance
This weld nut adheres to UNF thread standards with Class 2B thread fit for consistent dimensional accuracy. Manufactured to ASME B18.2.2 specifications, it ensures compatibility with standard 7/8"-14 fasteners. The product is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting stringent environmental and safety protocols for industrial use.
