Which characteristic describes Torx-head screws?

Torx-head screws are identified by their unique design featuring a six-point star-shaped head. This shape allows for a more efficient transfer of torque compared to traditional screw types, reducing the likelihood of stripping the screw or the tool. The six-point configuration helps distribute the pressure evenly, providing better grip and control during fastening.

This design is particularly advantageous in applications requiring precise torque specifications, making Torx screws a common choice in automotive and electronic assemblies. Additionally, the star shape helps reduce slippage and cam-out, which can be an issue with other screw designs, enhancing overall performance and durability.

The other choices present alternative features that do not accurately describe Torx-head screws.
