Professional Applications & Engineering Value

This M24 hex head screw is engineered for demanding industrial applications where corrosion resistance and structural integrity are paramount. The hot-dipped galvanized steel construction provides a robust barrier against moisture and chemicals, extending service life in infrastructure, heavy machinery, and construction frameworks. With a Class 10.9 strength grade and 150,000 psi tensile strength, it effectively handles high-vibration and dynamic loads, preventing joint failure. The partially threaded design and coarse metric thread ensure precise clamping over the 91mm grip length, reducing the risk of loosening in steel-to-steel connections. Ideal for external hex drive systems, it offers quick installation with standard tools, enhancing productivity in assembly lines and maintenance operations.

Specification Summary & Compliance

The fastener features a metric M24 x 3mm thread with Class 6g thread fit and right-hand direction, adhering to precise dimensional tolerances per DIN 6914 and ISO 7412 specifications. It is manufactured to meet Class 10.9 strength requirements and Rockwell C32 hardness, ensuring consistent performance under stress. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms its suitability for environmentally conscious projects, free from restricted substances.
