Three of the most common shapes of screw heads are the flat head, round head, and the ___ head.

• A. Oval
• B. Hex head
• C. Phillips head
• D. Slotted head

Answer: (A)

Head shapes describe how the top of the screw looks and how it sits in the material. Three common wood screw head shapes you’ll encounter are flat head, round head, and oval head. The oval head fits here because it’s a standard finish profile—slightly rounded with a longer, elongated shape that sits between the flat, flush look of a countersunk head and the more domed appearance of a round head. The remaining options aren’t head shapes but drive types: hex head refers to a hexagonal exterior for a wrench, while Phillips and slotted describe the drive recess used to turn the screw, not the overall head contour.
