Which description best defines a standard screwdriver?

• A. A screwdriver that has a flat blade at one end of the shank (the other end of the shank goes into the handle)
• B. A screwdriver with a cross-shaped head
• C. A screwdriver with a hex tip
• D. A screwdriver with a rounded tip

Answer: (A)

A standard screwdriver is the flat-blade, or slotted, type. Its blade is flat and fits into a single straight slot on the screw head, allowing you to turn the screw by applying torque along the flat surfaces. This distinguishes it from other screwdrivers: a cross-shaped head fits Phillips screws, a hex tip fits hex socket screws, and a rounded tip wouldn’t properly engage a straight slot. The flat-blade design is the classic, widely recognized form used for many traditional screws, making this description the best fit for defining a standard screwdriver.
