• Optimized installation efficiency through external hex drive design and 36mm head width, enabling secure tool engagement and rapid assembly
• Precise thread engagement with Class 6g thread fit and M24x3mm coarse threading, providing consistent clamping force and vibration resistance
• Full-length threading versatility allowing complete penetration through materials and uniform stress distribution along the entire 65mm length
• International compliance assurance meeting ISO 4017/DIN 933 specifications for guaranteed dimensional accuracy and interchangeability
• Environmentally responsible manufacturing with RoHS 3 and REACH compliance, ensuring safe usage across regulated industries

Professional Applications & Engineering Value

This M24 hex head screw delivers critical engineering solutions where high tensile strength and reliable fastening are paramount. The Class 10.9 steel construction combined with Rockwell C32 hardness addresses common failure points in heavy machinery, structural steel connections, and industrial equipment by resisting elongation under load and maintaining clamp force. The metric coarse thread with 3mm pitch ensures rapid installation in thick materials while the fully threaded design provides consistent holding power across the entire 65mm length. External hex drive configuration offers superior torque transmission for critical bolted joints in construction, manufacturing, and infrastructure projects where vibration resistance and long-term reliability are essential.

Specification Summary & Compliance

Manufactured to ISO 4017/DIN 933 standards with Class 6g thread fit tolerance for precise dimensional accuracy. The fastener meets Class 10.9 strength requirements (150,000 PSI tensile) and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features M24x3mm coarse threads with right-hand direction and 65mm fully threaded length for consistent performance across industrial applications.
