Standard drywall screws have a curved taper. The curved taper of a drywall screw allows the screw to guide itself without punching through the paper covering your drywall.

If you are attaching your drywall to wood, you should get drywall screws that have threads that are spaced farther apart.

If you are attaching your drywall to a light-gauge steel frame, then you need drywall screws that have threads that are closer together.

If you are attaching your drywall to steel frame that is heavier than 20-gauge you need drywall screws that are self-tapping with threads that are close together.
