Professional Applications & Engineering Value

Engineered for heavy-duty industrial fastening, this M24 Class 10.9 steel hex head screw addresses critical challenges in construction, machinery assembly, and structural engineering. The metric coarse thread (3mm pitch) and fully threaded design provide superior resistance to vibrational loosening, a common failure point in dynamic loads. The black oxide finish not only enhances corrosion resistance but also reduces galling during installation, prolonging tool life. With its external hex drive and high tensile strength, it delivers reliable performance in bolted connections requiring precise preload and fatigue resistance, making it ideal for applications like steel framing, industrial equipment, and automotive subsystems where ISO 4017 compliance is mandated.

Specification Summary & Compliance
