TOPLoc® Fascia Drill Bit

Designed with efficiency, quality, and your deck’s clean appearance in mind, the unique Fascia Bit — made exclusively for TOPLoc™ Fascia Fasteners — overdrives and countersinks the fascia fastener hole in one step, while significantly reducing oil-canning.

Compatible with all TimberTech PRO and TimberTech EDGE boards.


Preserves Pristine Surfaces

Eliminates the effect of oil-canning that can take away from a deck’s clean look.

Forward-Thinking Design

An imaginative solution to fascia fastening and deck protection, with a bit that pre-drills and overbores through the hole.
