• Easy installation and removal through external hex drive design with standard 22mm head width for common tool compatibility
• Full thread coverage along the 40mm length maximizes load distribution and clamping force
• International standard compliance with ISO 4017/DIN 933 specifications guarantees interchangeability and quality assurance
• Optimized coarse thread pitch (M14x2mm) enables faster assembly and reduced cross-threading risks

Professional Applications & Engineering Value

These high-strength metric hex head screws deliver critical performance in demanding industrial settings where failure is not an option. The Class 10.9 steel construction with Rockwell C32 hardness provides exceptional resistance to shear and tensile forces, making them ideal for heavy machinery, structural steel connections, and automotive assemblies. The zinc yellow-chromate plating creates a robust barrier against corrosion in outdoor or chemically aggressive environments. With fully threaded M14x2mm coarse pitch design and Class 6h thread fit, these fasteners ensure reliable clamping force distribution and minimize installation time while maintaining precision alignment in critical joints. The external hex drive configuration allows for high torque application using standard tools, reducing assembly labor costs while providing secure, vibration-resistant connections.

Specification Summary & Compliance

This M14 hex head screw features precise Class 6h thread fit tolerance per ISO metric standards, ensuring consistent performance across applications. The fastener is manufactured to ISO 4017/DIN 933 specifications with complete dimensional compliance, including 40mm length, 22mm head width, and 8.8mm head height. The right-hand coarse thread (M14x2mm) and fully threaded design provide optimal engagement characteristics. Manufacturing follows international quality standards with RoHS and REACH compliance for environmental safety, while the material properties meet Class 10.9 strength requirements equivalent to 150,000 psi tensile strength.
