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. Typically manufactured from high-strength materials such as stainless steel or carbon steel, T-head screws are designed to endure significant load and stress. 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.

The self-tapping property of these screws lies in their thread design. The sharp cutting edges on the screw's thread cut into the material, creating a mating thread as it is screwed in. This mechanism ensures a secure grip, minimizing the risk of stripped threads or loose connections. Moreover, due to their plastic composition, nylon self-tapping screws can be easily removed and reinserted without damaging the surrounding material, a characteristic that metal screws often lack.
