Professional Applications & Engineering Value

This M20 hex head screw delivers critical engineering solutions for heavy-duty industrial applications where failure is not an option. The Class 10.9 steel construction provides exceptional tensile strength that withstands extreme mechanical stresses in construction machinery, structural steel connections, and industrial equipment assembly. The metric coarse thread with 2.5mm pitch ensures rapid installation while maintaining secure fastening, significantly reducing assembly time in production environments. The blue-dyed zinc plating offers both visual inspection benefits and superior corrosion protection, making it ideal for outdoor applications or environments with exposure to moisture and chemicals. The partially threaded design allows for precise clamping force distribution, preventing joint loosening under vibration while accommodating thermal expansion in metal-to-metal connections.
