The T-head screw's defining feature is its T-shaped head, which provides a larger surface area than traditional screws. This configuration enables better load distribution and greater resistance to pull-out forces.

The screw's threading, which can be either coarse or fine depending on the required application, ensures a secure fit. Moreover, the T-head allows for easy installation using standard tools, making it user-friendly for both professionals and DIY enthusiasts.
