Using one of the drills listed below and the Cortex setting tool, drive the Cortex deck fastener to the preset level below the deck surface. Continuously drive the fastener at one speed until the setting tool disengages on its own. Do not stop and start the drive as this may affect the finished appearance. It is important that the Cortex screw is driven perpendicular to the deck, with two screws per joist. The setting of the Cortex screw creates a cored hole in the deck surface. Place the Cortex engineered plug into the hole with the deck surface side up. Gently tap the deck plug into the cored hole until the plug is flush with the deck surface.
Install the Cortex fastener using one of these suggested drills:
- Corded drill with 1/2" chuck
- Cordless drill with 1/2" chuck and 18V battery
- Impact drill
