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.

Industries that use self-drilling screws for metal fastening include automobile construction, building, and furniture manufacturing.

The design and construction of self-drilling screws allows them to pierce 20 to 14 gauge metals.

Self tapping screws tap their own thread, so they need a pilot hole slightly smaller than the screws diameter.

The idea is, you drill a pilot hole into wood or another soft material.

Then as you drive the tapping screw in, its threads will dig into the material keeping it secure.
