Professional Applications & Engineering Value

This M16 hex head screw is engineered to address critical challenges in heavy-duty industrial applications such as structural steel connections, machinery assembly, and construction frameworks. The hot-dipped galvanized steel material provides a robust barrier against rust and corrosion, significantly extending service life in outdoor or high-moisture settings. Its Class 10.9 strength grade and 150,000 psi tensile strength ensure that fasteners maintain integrity under dynamic and static loads, reducing the risk of joint failure. The partially threaded design with a defined 122mm grip length allows for precise clamp load control, minimizing stress concentration and enhancing the stability of assembled structures. By integrating coarse threading (M16x2mm) and an external hex drive, these screws enable quick, tool-friendly installation, streamlining assembly processes while meeting rigorous DIN 6914/ISO 7412 standards for consistent quality and performance.
