Answer:
Hold the tip of the screwdriver with one hand as you turn its handle with the other. Grasp the handle with your dominant hand and the tip with your other as close to the head of the screw as you can.

When you’re using a Phillips-head screwdriver, make sure that you’re not doing it the hard way. Here’s how. Be sure you’re using the right size screwdriver.

You’ll damage the screw and the driver.
