You can tighten a screw with a screwdriver, but you can also make it easier by using an electric screwdriver. Bosch screwdrivers are light and compact and ideal for light-duty screw jobs, such as putting together a cabinet or table. Thanks to the battery operation, you can easily take your Bosch screwdriver throughout the house. The smart design also ensures that you also tighten those small screws at the top of the new bookcase.
