Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these M20 hex head screws deliver reliable performance in construction, machinery, and structural steel connections. The hot-dipped galvanized steel material provides a robust barrier against moisture and chemicals, addressing common failure points in outdoor or corrosive settings. With a Class 10.9 strength grade and Rockwell C32 hardness, the screw maintains integrity under high vibration and dynamic loads. The metric coarse thread (2.5mm pitch) ensures rapid installation without cross-threading, while the partially threaded design concentrates clamping force where needed. Ideal for DIN 6914/ISO 7412 compliant frameworks, this fastener simplifies procurement and reduces downtime in critical assemblies.
