Description

 

Self-drilling Screw similar to sheet metal screws, but they have a drill-shaped point to cut through sheet metal or steel which eliminates the need for drilling a pilot hole. These self-drilling screws are designed for use in soft steel or other metals.Self-drilling screw points are numbered from 1 through 5, the larger the number, the thicker metal it can go through without a pilot hole. A 5 point can drill a 0.5 in (13 mm) of steel, for example.

 Compare to Self Tapping Screw

 

(1) Self Drilling Screw

Self drilling describes it very well. These screws work as both a drill bit and a fastener. Self Drilling Screw do not need a pilot hole because of the drill bit end. They work quite well at fastening thin pieces of metal together and were designed for exactly this reason. We have customers use these when doing frame work on their cars, or attaching sheet metal to a metal frame. Why drill a bunch of holes into a metal sheet wearing out a drill bit, when you can use these guys. They also have much variance in types and uses than tapping screws.

 

(2)Self Tapping Screw

Self tapping screws tap their own thread, so they need a pilot hole slightly smaller than the screws diameter. The idea is, you drill a pilot hole into wood or another soft material. Then as you drive the tapping screw in, its threads will dig into the material keeping it secure. Self tapping screws are ideal for all sorts of materials, including wood, metal, and brick. For harder surfaces, self tapping screws might have little notches on the thread to help cut the thread, just like a tap. Not all tapping screws have a pointy tip, some will be blunt or flat.
