Professional Applications & Engineering Value

These M24 hex head screws deliver critical engineering solutions where high tensile strength and corrosion resistance are paramount. The Class 10.9 steel construction with Rockwell C32 hardness ensures reliable performance in structural applications, heavy machinery, and industrial equipment subjected to dynamic loads and vibration. The zinc yellow-chromate plating provides essential protection against environmental degradation, while the metric coarse thread (M24x3mm) design enables rapid assembly in time-sensitive production environments. The fully threaded configuration distributes clamping force evenly, preventing joint loosening in critical connections. These industrial fasteners are engineered to maintain integrity under continuous stress, reducing maintenance frequency and downtime in demanding heavy-duty applications.

Specification Summary & Compliance

This hex head screw features precise Class 6h thread fit tolerance according to ISO metric standards, ensuring consistent threading performance. The fastener complies with DIN 933 and ISO 4017 manufacturing specifications for dimensional accuracy and mechanical properties. The M24x3mm coarse thread with right-hand direction follows international threading standards for compatibility with existing industrial components. Manufacturing processes adhere to quality control measures that support compliance with RoHS and REACH environmental regulations, while the mechanical properties meet the rigorous requirements of Class 10.9 strength classification for industrial fastening applications.
