Brass self-drilling screws are specialized fasteners made from brass, a metal alloy primarily consisting of copper and zinc. The self-drilling feature indicates that these screws come with a drill-shaped tip, allowing them to create their own pilot holes as they are driven into materials. This design eliminates the need for pre-drilling, significantly speeding up the installation process. Brass screws are typically used in environments where corrosion resistance and visual appeal are crucial, making them ideal for a variety of applications.

The M20 Chemset anchor is a chemical anchor that is used to fasten bolts, rods, and other fixtures into concrete, brick, or masonry. It is designed to provide a superior bond strength compared to traditional mechanical anchors. The anchor consists of a resin cartridge and a steel rod or bolt. The resin is injected into the hole drilled into the substrate, where it cures and forms a strong bond with the surrounding material. This creates a secure connection that is capable of withstanding high loads and forces.
