Self-drilling screws, also known as tek screws, are designed with a unique that eliminates the need for a pre-drilled pilot hole. This feature saves time, effort, and reduces the risk of material splitting, making them an ideal choice for DIY enthusiasts and professionals alike. The sharp tip, usually accompanied by threading near the head, allows the screw to pierce through the wood effortlessly while the rest of the thread bites into the material, providing a secure hold.

Wafer head reamer self-drilling screws are specialized fasteners designed to penetrate materials without the need for pre-drilled holes. The wafer head refers to its flat, wide design, which provides a large bearing surface. This shape helps distribute the load over a broader area, reducing the risk of material deformation and enhancing overall stability. The reamer design, on the other hand, refers to the screw's cutting capability, allowing it to create its own hole while drilling into various substrates.
