Self Drilling Screw

1. Self-drilling screws, also known as "TEK" screws, are special fasteners often used for wood, metal or PVC construction applications. These screws are designed to securely fasten two materials together with one installation step and without the need for pre-drilling, separate tools or operations.

2. Self drilling screws feature a sharp drill point at the tip, which is followed by a single thread body and a tapping screw thread. This unique design allows the screw to drill into material, while the tapping thread further cuts away material, all in one motion as the screw is driven in.

3. The self drilling screw is designed to cut its own threads into the materials being fastened, eliminating the need for additional tapping or drilling. And while a self-drilling screw can be installed much faster than other types of fasteners, the job is still done correctly and securely.

4. Self-drilling screws come in a variety of shapes, styles and sizes, all designed to drill and tap into materials such as aluminum, steel and even plastics. Many styles also feature proprietary coatings and rust-resistant finishes for higher performance and durability.
