Feature:- Self-drilling screw, in addition to the tap-like flute in the leading threads, there is also a drill-like fluted tip that looks much like the tip of a center drill. These screws combine a threading-like action and the fastener installation itself into only one driving motion (instead of separate drilling, tapping, and installing motions); they are thus very efficient in a variety of hard-substrate applications, from assembly lines to roofing.
