- Left-hand threading provides secure fastening in applications where standard right-hand threads may loosen due to rotational forces.
- Fully threaded UNC coarse design offers faster installation and superior grip in a wide range of materials, improving assembly efficiency.
- Grade 5 steel construction with Rockwell C21 hardness delivers excellent durability and resistance to wear, extending service life in demanding environments.
- External hex drive and hex head design allows for easy installation and removal with standard tools, minimizing assembly time.
- Compliance with ASME B18.2.1 and SAE J429 standards guarantees consistent quality and interchangeability for industrial applications.
- RoHS 3 and REACH compliance ensures environmental safety and regulatory adherence for global supply chains.
Professional Applications & Engineering Value
This Grade 5 steel hex head screw is engineered to address critical challenges in heavy-duty industrial settings, such as machinery assembly, automotive systems, and construction projects. The left-hand thread is particularly valuable in applications subject to counter-clockwise rotation, preventing unintended loosening and enhancing safety. Made from high-strength steel with a Rockwell C21 hardness, it resists deformation under load, while the UNC coarse threading ensures quick, secure fastening in coarse-grained materials. Its fully threaded design and external hex drive simplify installation, reducing labor costs and improving reliability in industrial hex screw applications where vibration and high stress are common.
Specification Summary & Compliance
This fastener features a 1/2"-13 UNC coarse thread with Class 2A fit for standard tolerance and easy assembly. It meets ASME B18.2.1 and SAE J429 specifications, ensuring dimensional accuracy and performance consistency. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it supports environmentally responsible sourcing and use in various industries.
