Self-drilling screws, a type of self-tapping screw, are threaded fasteners that drill their own hole and thread it as they are installed. Usually only recommended for use with metal, self-drilling screws are available with wings that enable use when fastening wood to metal. The drill point length should be long enough to penetrate both materials being fastened before the threading portion reaches the material.

Self-Drilling Screws with a point "like a drill bit", these screws create their own hole, and their own thread in one action. 
Self-Drilling Screws are also commonly called 'Tek' screws, a proprietary brand name associated with their unique shape and function.
Drill point sizes dictate drilling capacity. Common Tek point sizes are #2, #3, #4 and #5 (Series 500) - 2 and 3 most common, 4 and 5 for going through thicker metal.

Most common uses -

 HVAC - duct, clips and brackets
