Hexagonal head self drilling screw
A Self-drilling screw is, essentially a self-tapping screw with the added feature of a drill point end. Self-drilling screws eliminate the need for a pre-drilled pilot hole as they perform the drilling, tapping, and fastening in one action. Hardened steel fixings are generally used when fixing metal to metal or metal to timber.
How To Choosing A Self Drilling Screw
A self drilling screw makes a hole in the material it is inserted into. A self tapping screw, on the other hand, will make its own thread as it is driven into the material.
