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.

One of the key advantages of self drilling screws is their efficiency and convenience. Traditional screws require the user to drill a hole before inserting the screw, a process that can be time-consuming and labor-intensive. With self drilling screws, this step is eliminated, allowing for faster and more efficient installation. This makes them an ideal choice for professionals and hobbyists alike who are looking to save time and streamline their projects.
