1. Descriptions: 

 

     Self Drilling Screws are installed with a standard power driver…each screw drills its own hole, taps its own threads, and then fastens the material…all in a single operation. Frequently used with sheet metal as well as stainless steel, aluminum, brass and plastic. Threads are coarse. Length is measured from under the head for Hex, Hex Washer, and Pan head styles. For Flat Wafer Head, length measurement includes head.

3. Applications:

 

      Hex Washer Head Self drilling screws, also known as Tek screws, are fasteners with a special pointed end style that allows them to penetrate thin materials without a starting or pilot hole. Also known as self tapping screws or self drilling bolts, they cut or form threads to engage with the mating material.
