One advantage of the Torx screwdriver is that it can be used to tighten any type of screw.

• A. Yes
• B. No
• C. Sometimes
• D. Only certain screws.

Answer: (B)

Torx bits are designed to engage Torx screws with a star-shaped pattern. This geometry provides a larger contact area and less cam-out, so you can apply higher torques with less slipping when turning a Torx head. But that advantage only applies to Torx fasteners. The bit won’t fit or properly engage slotted, Phillips, square/Robertson, hex, or other screw drives, and forcing it can damage both the screw head and the bit. So the statement that a Torx screwdriver can tighten any type of screw is not true.
