self drilling screws for heavy steel

Self-drilling screws are equipped with a cutting point at their tip, which functions like a drill bit, allowing them to pierce through metal, wood, or plastic effortlessly. This eliminates the need for a separate drilling process, thereby saving time and increasing productivity on the job site. The threads on the screw's body then engage with the substrate material, providing a secure hold, and preventing any slippage or loosening over time.

One of the key features of security tek screws is their unique design, which includes a specialized head that requires a matching tool for installation and removal. This tool, often referred to as a security bit or drive, has a specific shape that fits into the head of the screw, allowing it to be tightened or loosened. Without the correct tool, it is nearly impossible to tamper with security tek screws, making them an ideal choice for high-security environments.

Metal expansion nuts, often referred to as expansion anchors or expansion inserts, are specialized fasteners that expand when a bolt or screw is threaded into them. They typically consist of a cylindrical body with slits along its length or an expandable design that facilitates outward expansion. The main purpose of these nuts is to create a secure grip within a substrate, such as concrete, wood, or metal, thereby preventing loosening due to vibrational forces, temperature fluctuations, or stress.
