How to Select a Drill Point Size

Tek(R) screws, are also known as self drilling screws, but are not to be confused with self-tapping or sheet metal screws which do not pre-drill. A self-drilling screw has a very small carving at the end of its tip called a drill bit. These screws drill their own hole and then tap threads to combine two or more pieces of material together without pre-drilling. This is done with nothing more than a standard power drill motor. Depending on the thickness of the material you are drilling into, you have several drill points available, the longest being a Tek 5.
