Which of the following terms refers to screws that behave like a tap?

Thread-cutting screws are specifically designed to create their own threads as they are driven into a material. This behavior is akin to a tap, which cuts threads into a pre-drilled hole. When a thread-cutting screw is inserted, its specially shaped threads effectively carve out a path in the material, achieving a secure fit without the need for a pre-existing hole with threads.

This threading action is essential in materials that may not have enough structural integrity to support standard screws, allowing for a tighter grip and reducing the risk of loosening. Therefore, thread-cutting screws are ideal for applications where creating a strong, precise thread is crucial.

In contrast, thread-forming screws are designed to deform the material they are inserted into to create threads without cutting it, which differentiates them from the behavior exhibited by taps. Torque screws have a focus on torque management rather than thread creation, and hexagon screws refer to the shape of the head rather than their threading behavior.
