Self-drilling bolts feature a unique point design that allows them to pierce through materials such as metal, wood, and plastics. The shaft of the bolt is crafted to have threads that grip the material securely once the bolt is installed. This eliminates the need for pre-drilling, saving time and labor costs. The design often includes a cutting tip that facilitates penetration and minimizes damage to the surrounding material, ensuring a clean and reliable connection.

On the other hand, the 16% self-drilling screws are specifically engineered for use on thicker metal sheets, typically ranging from 0.375 to 0.500 inches in thickness. These screws have a higher drilling capacity and are designed to provide a secure and stable connection. The 16% self-drilling screws are commonly used in heavy-duty construction projects, such as steel frame buildings, bridges, and infrastructure development The 16% self-drilling screws are commonly used in heavy-duty construction projects, such as steel frame buildings, bridges, and infrastructure development5 The 16% self-drilling screws are commonly used in heavy-duty construction projects, such as steel frame buildings, bridges, and infrastructure development The 16% self-drilling screws are commonly used in heavy-duty construction projects, such as steel frame buildings, bridges, and infrastructure development55 16 self drilling screws. Their coarse threads and self-piercing design allow them to penetrate thick metal sheets with ease, ensuring a strong and reliable hold.
