The Cross Countersunk Head Screw is a precision-engineered machine screw designed for applications requiring a flush, smooth surface finish. Manufactured to GB819 standards from high-quality 304 stainless steel, this fastener offers excellent corrosion resistance, durability, and strength. Its countersunk head shape ensures that the screw sits flush with the surface after installation, delivering both functionality and a clean aesthetic. The cross recessed drive (Phillips) allows easy installation with secure torque transfer, minimizing the risk of slipping. These screws are widely utilized in electronics, machinery, furniture assembly, and other applications where a clean, flush aesthetic and reliable fastening are essential.
