Do you need a pilot hole for self drilling screws?

 While self-tapping screws will tap a hole into a soft material, self-drilling screws are capable of drilling a hole into anything from metal to wood. This key difference is self-drilling screws have a tip like a drill bit, so they do not need a pilot hole.


 










What is the difference between self drilling and self tapping screws?

Self-drilling screws eliminate the need for a pilot hole, but can tap as well. Self-tapping screws tap their own threads, but cannot drill through metal and require a pilot hole. These screws are not interchangeable, and mixing up the two can cause many headaches or possible failures in the field.
