Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these M27 hex head screws combine Class 10.9 strength with hot-dipped galvanized steel to solve critical challenges in construction, machinery, and infrastructure. The coarse metric thread (3mm pitch) ensures rapid installation in high-vibration environments, while the partially threaded shank concentrates clamping force precisely where needed. With 150,000 psi tensile strength and corrosion-resistant coating, they prevent joint failure and reduce maintenance in demanding settings like structural steelwork, heavy equipment assembly, and outdoor installations exposed to moisture and chemicals.
