Professional Applications & Engineering Value

This 1/2"-13 UNC hex head screw is engineered to solve critical challenges in heavy machinery, structural steel framing, and industrial equipment assembly. The 18-8 Stainless Steel material provides excellent resistance to rust and oxidation, which is vital for outdoor applications or in corrosive atmospheres, thereby extending service life and reducing maintenance downtime. The coarse thread and Class 2A thread fit ensure rapid installation and robust holding power in wood, metal, and composite materials. Its partially threaded design concentrates clamping force where it's needed most, preventing joint loosening under vibration. With an external hex drive and substantial head size, it accommodates high torque tools, making it a reliable choice for construction, manufacturing, and infrastructure projects where heavy-duty fastening integrity is non-negotiable.

Specification Summary & Compliance

This screw features a 1/2"-13 UNC coarse thread with a Class 2A thread fit for standard tolerance and easy assembly. The dimensional and mechanical properties conform to the ASME B18.2.1 standard. It is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and suitable for use in regulated markets.
