Keep the driver directly in line with the screw, with the shaft directly over the screw head. The driver and screw should be “on-axis,” forming a straight line.

Holding the driver at an angle creates a poor fit between the driver and the screw head. Result: slippage and probable damage to the screw.

Sometimes the screw itself needs to go into the surface at an angle. Keep the driver positioned correctly relative to the screw, rather than the surface it’s going into.
