• A. False
• B. Not true
• C. Slotted and Phillips slots are the most common for screw heads
• D. Torx is the most common

Answer: (C)

Understanding which screw head types dominate in everyday use. Slotted screws are the oldest and simplest, commonly found in basic hardware and traditional woodworking, while Phillips heads became the standard for many consumer and construction applications because they handle torque well and work reliably with common drivers. Together, they cover a vast majority of screws you’ll encounter in furniture, cabinetry, electronics, and general repairs, which is why they’re described as the most common. Torx heads offer excellent torque transfer and cam-out resistance, but they aren’t as widespread across all general-use screws as slotted or Phillips are, so they aren’t the most common overall. Therefore, the statement is true: slotted and Phillips slots are the most common for screw heads.
