The Metal Butterfly Screw, often referred to as a butterfly nut, is a type of fastener distinguished by its unique shape resembling a butterfly's wings. This design choice is not merely cosmetic; it serves a practical purpose. Its broad, flat surfaces provide an extensive contact area, ensuring a secure and evenly distributed grip when tightened or loosened. The symmetrical structure allows for easy manipulation, even in tight spaces, making it a popular choice in various industries, from automotive to aerospace.

In addition to their self-drilling feature, these screws also come with various security enhancements to prevent tampering. For example, some self-drilling security screws are made with a unique head design that requires a special tool, such as a security bit or driver, to tighten or loosen. This makes it nearly impossible for someone without the proper tool to remove the screws, adding an extra layer of security to the installation.

The installation process of chemical anchors is relatively straightforward but requires precise execution. First, a hole is drilled into the substrate. The hole must be clean and free from dust or debris to ensure optimal bonding. The resin and hardener are then mixed according to the manufacturer's instructions, and the mixture is injected into the drilled hole. Next, the anchor is inserted, and the setting time—typically a few minutes to a few hours, depending on environmental conditions and specific product guidelines—is allowed for the adhesive to cure. This method ensures a secure hold that can be trusted for carrying significant loads.
