Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this M24 hex head screw delivers critical performance where failure is not an option. The Class 12.9 steel construction, combined with fully threaded metric coarse threads, provides superior clamping force and vibration resistance in machinery, structural steel connections, and construction frameworks. Its high tensile strength and Rockwell C39 hardness prevent stripping and fatigue under dynamic loads, while the external hex drive allows for high-torque installation with standard tools. By meeting ISO 4017 specifications, it ensures reliability in global supply chains, reducing downtime and maintenance costs in sectors like automotive, manufacturing, and infrastructure.
Specification Summary & Compliance
This fastener adheres to ISO 4017 (DIN 933) dimensional and performance standards, with Class 6g thread tolerance for precise fit. It is manufactured from high-grade steel, heat-treated to achieve Class 12.9 strength and Rockwell C39 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for environmentally conscious industrial use.
