There are many different types of screwdriver, each one a perfect fit with a specific type of screw head. Used correctly they will drive and remove many thousands of screws without damaging either the screw head or the screwdriver tip.

Problems usually arise when a screwdriver is used with the incorrect type or size of screw. At first glance, philips, pozidrive and JIS Type S screws all look very similar, but only the correct driver will ensure a positive fit and effective transmission of torque to the screw.
