4. Variety of Heads and Coatings Tek screws come in various types of heads (such as hex, pan, or round) and can be coated in materials like zinc or epoxy for increased resistance to rust and corrosion. This allows for customization based on the specific needs of a project.

5. Reduced Risk of Damage Since self-drilling screws eliminate the need for pre-drilling, there is a lower risk of splitting or damaging the material being fastened. This is especially important when working with thick metal sheets, as even minor damage can compromise the integrity of the overall structure.

3. Easy Installation While they may seem complex, butterfly screws are straightforward to install. Once you've drilled the appropriate hole and inserted the screw, simply pull the toggle wings back into place, and you’re ready to mount your TV.

- Minimal Damage Because they expand rather than rely solely on friction, they minimize the risk of damage to the surrounding substrate.

Each type of bracing has its own unique advantages and applications, depending on the specific requirements of the steel structure. By carefully selecting and designing the appropriate bracing system, engineers can ensure the structural integrity and performance of steel structures in various loading conditions.

In automotive applications, metal expansion nuts are utilized in securing engine components and exhaust systems, where high temperatures can lead to expansion. Their reliability ensures that parts remain firmly attached, reducing the risk of failure.

3. Versatility CSK head self-drilling screws can be used in various materials, including metal, wood, and plastic. Their versatility makes them a preferred choice for both residential and commercial construction projects.
