Our self-drilling screws come in a wide variety: from flat heads to pan and round heads, from short to long points, to perform light to heavy duties. We make them in multiple materials such as zinc, black phosphate, stainless steel, and copper steel, often welding two metals together to achieve optimal drilling performance.
