The standard (straight slot) screwdriver is designed for use with screws that have

• A. A straight slot cut into the head
• B. Five-point star slots
• C. Torx heads
• D. Hex sockets

Answer: (A)

The main idea is that screwdrivers are matched to the shape of the screw head. A straight-slot screwdriver has a flat blade that fits into a single straight groove across the screw head. When you align the blade squarely with that slot and apply torque, the blade sits snug in the groove and turns the screw effectively, minimizing slippage and reducing the chance of damaging the slot. If the screw head is not a straight slot—such as a star-shaped (five-point or similar) pattern, Torx, or a hex recess—the straight blade won’t engage properly. Those heads require their respective drivers (star/Torx, or hex) to transfer torque safely and effectively. Using the wrong driver can cause the blade to slip, strip the slot, or fail to turn the screw.
