Professional Applications & Engineering Value

These M20 hex head screws deliver critical performance in heavy-duty industrial applications where failure is not an option. The Class 10.9 steel construction provides exceptional resistance to vibration loosening and structural fatigue, making them ideal for machinery assembly, structural steel connections, and automotive components. The metric coarse threading with 2.5mm pitch ensures rapid installation while maintaining secure fastening in high-vibration environments. The blue-dyed zinc plating offers both corrosion protection and visual identification for quality control. With full threading along the 60mm length, these external hex drive screws distribute clamping force evenly, preventing joint failure in critical load-bearing applications across manufacturing, construction, and equipment maintenance sectors.

Specification Summary & Compliance

This M20 x 2.5 x 60mm hex head screw features Class 6g thread fit tolerance according to metric standards, ensuring precise engagement with mating components. Manufactured to ISO 4017 DIN 933 specifications with right-hand coarse threading and fully threaded design. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of restricted substances for global industrial use. The Class 10.9 strength rating and Rockwell C32 hardness validate the fastener's capability for high-stress applications requiring reliable mechanical performance.
