Finally, use appropriate torque when tightening screws down. A properly fastened screw will be snug, but not so tight that your driver starts to slip.

This is largely a matter of feel, so your technique will improve with practice.

Smaller screws generally require less torque; over tightening them can damage their threads.

Very small screws—such as those used in phones and tablets—require very little tightening force. As soon as you feel resistance, give it another quarter turn or less and then stop.
