A tek screw, also known as self-drilling screw, is equipped with a drill-like point that allows it to create its pilot hole as it is driven into materials. This eliminates the need for pre-drilling, which can streamline the construction process significantly. The 5 designation typically refers to specific measurement protocols related to the screw's dimensions and strength characteristics. However, the specific meaning of 5 often involves manufacturer specifications or industry standards, allowing for slight variations in size and application based on regional or production practices.

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.
