Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this M24 hex head screw delivers robust performance in construction, machinery, and structural steel connections. The hot-dipped galvanized steel material provides a thick, adherent zinc layer that combats rust and corrosion, extending service life in exposed or humid conditions. With a Class 10.9 strength grade and 150,000 psi tensile strength, it withstands high dynamic loads and vibrations, reducing maintenance needs. The coarse metric thread and partial threading ensure secure fastening in coarse-grained materials like steel and cast iron, while the external hex drive facilitates efficient installation with common wrenches, saving time and labor in assembly lines and field operations.
Specification Summary & Compliance
This screw features M24 x 3mm coarse threads with a Class 6g thread fit for precise metric tolerances. It meets DIN 6914 and ISO 7412 manufacturing specifications, ensuring dimensional consistency and reliability. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms adherence to environmental and safety standards, free from hazardous substances, making it suitable for global industrial use.
