Cortical Self-Tapping screws have 1-3 self-tapping lutes in the tip of the screw so the screw cuts its own thread in the bone when it is inserted so that no tapping is required.
Advantages include speed of use, less instrumentation needed (taps) and the screws can be removed and re-inserted if done carefully. It is worth noting that the self-tapping flutes must sit outside the bone cortex to achieve the maximum pull out resistance.
