Professional Applications & Engineering Value
This M24 hex head screw is engineered from high-grade steel to address critical challenges in heavy machinery, structural assemblies, and industrial equipment. The Class 10.9 tensile strength and Rockwell C32 hardness prevent failure under dynamic loads, while the coarse metric thread with 3mm pitch ensures quick, secure fastening even in vibrating conditions. The zinc yellow-chromate plating provides a robust barrier against corrosion, making it ideal for outdoor or humid environments. Fully threaded and compliant with ISO 4017/DIN 933, it delivers consistent performance in construction, automotive, and manufacturing sectors, reducing maintenance needs and downtime.
Specification Summary & Compliance
This fastener adheres to ISO 4017/DIN 933 specifications, with precise Class 6h thread fit for metric coarse threading (M24 x 3mm). It meets Class 10.9 strength grade requirements, ensuring high tensile and yield strength. The zinc yellow-chromate finish complies with RoHS and REACH environmental standards, providing enhanced corrosion protection without harmful substances.
