Let's get started...

Screws are used to hold any material together whether it is plastic, wood or metal. Screwdrivers are used both for fixing and removing the screws. When using a screwdriver, make sure it is the appropriate size for the job. The tip of the screwdriver should fit snugly into the groove of the screw. If your screwdriver is too wide, it may damage the wood, plastic or metal approximately the screw.

Before you purchase a screwdriver, know the different types of screwdrivers first. Screwdrivers mainly come in three types: Standard, Phillips and Square-tipped. The standard type screwdriver has a flat, straight blade. The Phillips screwdriver has a tip that looks like a plus sign. The square-tipped screwdriver is generally used on screws that have a square hole on their head. Choose the screwdriver that will provide you with both safety and comfort.

When doing home repair jobs involving screws, make sure that the screwdriver you use matches the screw head. You would not want your material damaged. The blade tip width of the screw head should be the same as that of the screwdriver's blade tip to ensure that the screwdriver's tip fits tightly in the slot.

Use nut drivers to drive hex-head screws. Use a jeweler's screwdriver for fine jobs such as working on computer parts or repairing eyeglasses. To prevent motion injuries, use ratcheting or electric screwdrivers for bigger home repair jobs. To have a good control while handling, choose screwdrivers with black oxide tips.

Buy screwdrivers with non-groove handles. Choose a screwdriver with at least a five-inch handle. Store your screwdrivers in a rack or pouch, with their tips showing or exposed. This way, you can easily identify and pick the appropriate screwdriver for the job. If the screwdrivers are for working on electrical equipment, make sure their handles are insulated and that they have a non-conducting shaft.
