The Self Drilling Screw has become a wonder of fastening efficiency in both construction and fabrication by combining drilling and fastening into one ingenious mechanism. Designed with a sharp self-tapping point, it requires no pre-drilling in metal and other hard materials. This flue-like shape of the structure speeds-up the material removal, thus achieving fast and secure connection. Versatility is not limited to application where it is used on metal roofing and steel structure assemblage. This is a modern fastener, which tremendously makes it easy to fasten, which leads to simplification of processes with an overall increased project efficiency. Self Drilling Screw testifies the ingenuity, making tasks simple and lifting the standards of construction and assembly.
