Professional Applications & Engineering Value
This Grade 5 steel left hand hex nut is engineered to address critical challenges in industrial settings where standard right-hand threads may loosen under specific rotational forces. Its 1/4"-28 UNF fine thread and Class 2B thread fit ensure tight, reliable fastening in high-vibration applications such as machinery, automotive assemblies, and rotating equipment. The left-hand thread direction is ideal for components that rotate counter-clockwise, providing a secure lock that prevents accidental disassembly. Made from high-strength steel, this nut offers excellent resistance to wear and corrosion, supporting long-term operational safety and reducing maintenance needs. Its compliance with RoHS and REACH standards makes it suitable for global industrial use, ensuring both performance and regulatory adherence.
Specification Summary & Compliance
This hex nut adheres to inch system standards with a 1/4"-28 UNF fine thread and Class 2B thread fit for precise dimensional accuracy. It meets Grade 5 strength specifications, ensuring high tensile and proof load capabilities. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for industrial applications without hazardous substances.
