16mm self drilling screws

At its core, the structure of a bolt consists of a few key components the head, the shank, and the threads. The head is the larger, often hexagonal or square part at one end of the bolt, designed to provide a surface for the application of torque when tightening or loosening the bolt with a wrench. The shank is the long cylindrical part that spans between the head and the threads, and it determines the overall length of the bolt. The threads are helical ridges that spiral around the shank, allowing the bolt to engage with a nut or a threaded hole, enabling a strong clamping force between joined parts.

Hex head self-drilling screws are characterized by their hexagonal head, which allows them to be driven using a wrench or a socket, providing an excellent grip and making them easy to install. What sets them apart is their unique ability to drill into materials without the need for pre-drilling, thanks to their sharp, self-tapping points. This feature not only saves time but also reduces the need for additional drilling equipment, making the installation process more efficient.
