Professional Applications & Engineering Value

These Class 10.9 metric flat head screws deliver critical performance in demanding industrial applications where strength, precision, and corrosion resistance are paramount. The blue-dyed zinc-plated alloy steel construction provides superior protection against environmental factors while maintaining 120,000 psi tensile strength for structural integrity. The fully threaded M3 x 0.5mm coarse pitch design ensures rapid installation and maximum thread engagement in metal assemblies, electronic enclosures, and machinery components. The standard 90° countersink angle creates flush surfaces that eliminate protrusions in precision equipment, while the 2mm hex drive enables secure torque application without cam-out. These industrial screws solve common fastening challenges by combining high-strength performance with regulatory compliance for global manufacturing requirements.
