Professional Applications & Engineering Value
These M24 hex head screws deliver exceptional engineering value in heavy-duty applications where reliability is paramount. The Class 8.8 steel construction combined with Rockwell C21 hardness provides the structural integrity needed for construction frameworks, machinery assembly, and industrial equipment. The partially threaded design concentrates the thread engagement where it's most effective, preventing stress concentration in non-threaded sections while the coarse metric thread ensures rapid installation and superior resistance to vibration loosening. The zinc plated finish offers critical protection against corrosion in outdoor or chemically aggressive environments, making these industrial fasteners ideal for infrastructure projects, manufacturing equipment, and transportation applications where long-term performance is essential.
Specification Summary & Compliance
This M24 hex head screw features precise Class 6h thread fit tolerance with 3mm coarse pitch threading and partial threading extending 54mm along the 80mm length. Manufactured to ISO 4014, DIN 931, and SAE J1199 standards, ensuring dimensional accuracy and mechanical properties. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting the latest international safety and sustainability requirements for industrial components.
