Self-tapping screws are made from high-strength materials, originally designed to handle a variety of materials, including metal, plastic, and wood. The ability to penetrate and form threads in the base material makes hex head self-tapping screws particularly useful for applications where traditional screws may fail or require additional components for anchoring.

Hex head self-drilling screws, often referred to as Tek screws, are designed with a hexagonal head that allows for easy tightening using a wrench or a socket. The self-drilling feature means that these screws come with a drill bit tip that can penetrate metal, wood, and other materials without the need for pre-drilled holes. This eliminates the need for additional tools, making installation faster and more efficient.
