Professional Applications & Engineering Value

These M4 socket head cap screws with integrated flat washers deliver critical engineering solutions for demanding industrial applications. The black-oxide alloy steel construction provides superior corrosion protection in manufacturing environments where exposure to moisture and chemicals is common. The fully threaded metric design with coarse M4 x 0.7mm thread pitch ensures rapid installation and reliable fastening in machinery, equipment frames, and automotive assemblies. The combination of 170,000 psi tensile strength and Rockwell C39 hardness makes these socket head screws ideal for high-stress applications where vibration resistance and joint integrity are paramount. The integrated washer eliminates separate component handling while providing consistent surface pressure distribution, preventing material deformation in precision assemblies.
