Q: Are the Cortex screws and TOPLoc screws the same?
A:

Although both are specifically designed for composite materials, the Cortex screws and TOPLoc screws are not the same, David.

The design and dimensions of these two fasteners differ from each other.

TimberTech TOPLoc fasteners have painted heads that complement all our decking colors. Check out this TOPLoc color chart to see which color is recommended for your TimberTech deck.  As you can see in the photo, TimberTech Cortex on the other hand has colored plugs that are set into the decking.

Check out the installation videos for TimberTech Cortex and TimberTech TOPLoc. Both are fantastic options – so the choice is all yours!
