Galvanized steel square head screw is a fastener with a square head shape and a galvanized surface.
Galvanized steel square head screw is mainly used in construction sites and other projects. Its characteristics are that the axial surface of the screw body is formed with axially extending screw teeth, and at least one cut groove is provided at its tail end. It makes the screw more convenient to install and use. At the same time, the square head shape provides a larger contact area, which helps to provide stable support and fixing effect during the installation process.
Galvanized steel square head screw is usually made of Q235, 45# steel, SUS304, SUS316, etc. The surface treatment is galvanized or hot-dip galvanized or stainless steel polished, which further enhances the corrosion resistance and aesthetics of the screw.
