To use this product effectively, start by drilling a hole in the desired location. Make sure the hole is the appropriate size for the anchor. Once the hole is ready, insert the anchor into it. After the anchor is in place, take the screw and begin to tighten it. As you tighten the screw, the anchor will start to expand. Continue tightening until the anchor has expanded and securely grips the material. This ensures a strong and stable hold, making it ideal for various applications.
