The installation of the sleeve anchor includes the following steps:
Step 1. First determine the installation location and mark it.
Step 2. Choose a drill bit of appropriate size to drill holes. The length of the hole should not be too deep or too shallow, otherwise it will affect the installation effect.
Step 3. After drilling the hole, clean up the debris in and around the hole.
Step 4. Insert the sleeve anchor bolt through the accessories that need to be installed, and smash the sleeve anchor bolt into the hole with a hammer. Be careful not to damage the nut and head thread.
Step 5. Use a socket or wrench to slowly tighten the nut until the anchor bolt cannot shake, indicating successful installation.
