How to install?

1. Thread the screw through the hole in the object you want to secure (such as a concrete wall), making sure the diameter of the hole matches the outer diameter of the expansion screw.
2. Thread a nut onto the expansion screw and insert it into the drilled hole. Then, use a wrench to tighten the nut, causing the expansion screw to grip the sides of the hole.
3. Continue tightening the nut with a wrench until it is fully tightened and cannot be turned further. This will cause the expansion screw to expand and provide strong support for the object.
