Expanding metal wall anchors, often referred to as expansion anchors or toggle bolts, are hardware devices used to secure objects to walls or ceilings. They are constructed from metal and feature a unique design that allows them to expand within the wall when screw tension is applied. This expansion locks the anchor in place, providing a strong hold that can support significant weight.

Screws are another essential type of structural fastener, distinguished by their helical threads. They provide excellent holding power when driven into materials like wood, metal, or plastic. Common screw types include wood screws, machine screws, and self-tapping screws. Wood screws are designed specifically for use in wooden materials, while machine screws are used in conjunction with nuts or tapped holes in metal. Self-tapping screws, on the other hand, create their own thread as they are driven into the material, eliminating the need for pre-drilling.

3. Bridge Construction The strength and reliability of M20 foundation bolts make them ideal for use in bridge construction, where they help secure various structural elements against the forces of wind and load.

In addition to their ease of use and versatility, self-drilling anchor screws offer several other benefits. For one, they provide a flush finish, resulting in a clean and professional look. This makes them ideal for applications where aesthetics are important, such as in interior design projects. Self-drilling anchor screws also have a high load-bearing capacity, making them suitable for heavy-duty applications.

Self-drilling screws, often referred to as Tek screws, are specialized fasteners that possess a unique drill point. This drill point enables the screw to create its own hole in the material, eliminating the need for pre-drilling. When combined with the galvanized coating, which provides excellent corrosion resistance, these screws become ideal for outdoor and high-humidity environments.
