What are Self Drilling Screws used for?

Self-drilling screws have a point that acts as a drill bit and sharp cutting threads that tap the hole during installation. Self-drilling screws are a commonly used variety of screw for quick drilling into both metal and wood. A self-drilling screw can typically be identified by its point and flute (notch) tip.

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 Tapping and Self Drilling 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.
