In old days, the only way to drive in a screw was with a handheld screwdriver, where the only torque was coming from your wrist. But with a portable handheld power screwdriver, you can now power-down a screw in just seconds. And we have the power screwdriver bits to let you screw down screws of all sizes. A torx screwdriver lets you tighten down a torx screw, which has a special 6-point head, and is used in automobiles, motorcycles, bicycles, computers, and other consumer electronic items. We have many torx bit set options for electric screwdrivers, and more. Besides screwdriver bits, Zoro also carries fastening tool accessories, impact wrench accessories, and electric impact wrenches.
