2. Ease of Installation Wedge bolts are designed for quick installation. Their tapered shape allows for easy insertion into pre-drilled holes in the formwork. This not only speeds up the construction process but also reduces labor costs, as fewer tools and less time are needed for assembly.

2. Corrosion Resistance Made from high-quality materials, these screws are highly resistant to rust and corrosion, ensuring longevity in challenging environments.

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.
