Self-tapping screws are a common type of mechanical connector, and their unique design allows for self-drilling and threading directly on metal or plastic substrates without the need for pre-punching during installation. This innovative design greatly simplifies the installation process, increases work efficiency, and reduces costs.
Self-tapping screws are usually made of high-strength steel, and the surface is treated with galvanization, chrome plating, etc., to increase their anti-corrosion performance and prolong their service life. In addition, they can also be coated according to different needs, such as epoxy coatings, to provide higher corrosion resistance and water resistance.
