There are three main types of screwdrivers: standard, which has a straight, flat blade; Phillips, which has a tip that looks like a plus sign; and square-tipped, which is used for recessed screws that have a square hole in the head. Several variations of these exist - choose the best one for your comfort and safety. Here are some guidelines.
Steps:
1. Match the screwdriver to the screw head.
2. Don't assume that all cross-head screws are for Phillips screwdrivers. A Phillips will slip out of a screw designed for a Pozidriv screwdriver, which has a slightly flatter tip.
3. Drive hex-head screws with nut drivers.
4. Do fine work, such as on eyeglasses and computer equipment, with a set of jewelers screwdrivers.
5. Find screwdrivers with contoured handles that are at least 5 inches long and that fit the shank tightly. Handles without finger grooves are the most comfortable.
6. Try an offset or a stubby screwdriver in close quarters where a normal screwdriver won't fit.
7. Get a ratcheting screwdriver or an electric screwdriver to prevent repetitive motion injuries.
8. Use a screwdriver that has the same blade tip width as the screw head and fits in the slot tightly.
9. Look for screwdrivers with black oxide tips, which improve control.
10. Use a screw holder or a magnetic screwdriver to start screws in awkward or hard-to-reach places.
Tips:
Store your screwdrivers in a rack or pouch that leaves the tips exposed; this way you can find the proper screwdriver quickly.
Warnings:
Keep in mind that rubber handles on screwdrivers are for comfort and grip. They aren't designed to protect the user from electrical shock. If you must work on live electrical equipment, be sure that your screwdriver has an insulated handle and a nonconducting shaft.
