Professional Applications & Engineering Value

This M16 hex head screw is engineered to address critical challenges in heavy-duty industrial and construction settings, where fastener failure can lead to costly downtime or safety hazards. The hot-dipped galvanized steel material provides a robust barrier against rust and chemical exposure, making it ideal for outdoor infrastructure, machinery frames, and structural steel connections. With its Class 10.9 high tensile strength and coarse metric thread design, it ensures secure, vibration-resistant fastening in dynamic loads—common in conveyor systems, bridgework, and equipment mounting. The partially threaded shank allows for precise clamp load distribution, minimizing stress concentration. Complying with DIN 6914 and ISO 7412, it guarantees dimensional accuracy and interchangeability, streamlining procurement and assembly processes for engineers and contractors.

Specification Summary & Compliance

The screw adheres to Class 6g thread fit per metric standards, ensuring precise tolerance for reliable engagement. It meets DIN 6914 and ISO 7412 specifications for dimensional and mechanical properties, and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications.
