One of the key features of security tek screws is their unique design, which includes a specialized head that requires a matching tool for installation and removal. This tool, often referred to as a security bit or drive, has a specific shape that fits into the head of the screw, allowing it to be tightened or loosened. Without the correct tool, it is nearly impossible to tamper with security tek screws, making them an ideal choice for high-security environments.

Self-drilling screws, also known as “Tek” screws, feature a unique design that incorporates a drill bit-like tip, allowing them to create their own hole as they are driven into materials. This feature eliminates the need for pre-drilling, saving time and effort during installation. Galvanized screws, on the other hand, are coated with a layer of zinc to enhance their corrosion resistance. This dual functionality makes self-drilling galvanized screws ideal for a wide range of applications, especially in outdoor and critical structural projects.

With their ease of use, 2-inch self-drilling screws can also contribute to reduced labor costs. By speeding up the installation process, fewer labor hours are required to complete a project. This efficiency can lead to significant savings, particularly in large-scale construction endeavors. Furthermore, with fewer tools needed—thanks to the elimination of pre-drilling—there is less reliance on multiple laborers to manage different aspects of the fastening process.
