drilled prior to use which cuts down on time needed to drill and fasten
materials by combining them. These have the same heads as traditional bolts and
screws, but the fastener is designed with a drill flute on the tip to
drill/fasten at the same time. Useful for quick sheet metal fastening and other
applications like metal to metal or wood to metal.

with short vertical sides. Phillips drives are + shaped for a phillips screw
