How to Use Concrete Screws

Step 1: Pre-drill a suitable hole
Begin by drilling a hole using the provided drill bit - concrete screws should be embedded in the base material to a depth of 1" to 1-3/4", and ensure the hole is 1/2" deeper than the screw embedment for a smooth installation.

Step 2: Secure with Concrete Screws
Drive the Concrete Screw into the hole perpendicularly.
Note: Excessive torsion leads to screw head separation or thread stripping in the base material.

Step 3: Installation Completed
The installation process is simple and convenient, you can also easily remove it when needed.
