Professional Applications & Engineering Value
This Grade 5 steel hex nut with a left-hand UNC coarse thread is engineered to address critical challenges in demanding sectors like machinery, automotive, and heavy equipment. The extra wide profile and external hex drive provide enhanced grip and torque resistance, reducing the risk of stripping under vibration or high loads. Made from robust steel, it offers superior strength to withstand extreme conditions, while the left-hand thread direction is essential for applications where standard right-hand threads may loosen due to rotational forces. This nut ensures reliable performance in assemblies requiring reverse threading, such as certain rotating shafts or safety-critical fasteners, delivering long-term durability and minimizing maintenance needs.
Specification Summary & Compliance
This hex nut features a 1/4"-20 UNC coarse thread with Class 2B thread fit for precise dimensional accuracy and easy assembly. It adheres to industry standards for inch system fasteners and is manufactured to meet Grade 5 strength requirements. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for various industrial applications.
