The Simpson Strong-Tie Fascia Screw Countersink bit is crucial to safe and proper installation of the fascia board.  The fascia bit bores a hole through the fascia material that is wider than the shank of the fascia screw.  The bit countersinks so the head of the screw is flush with the surface of the material.  Complete your project with a clean professional look that prevents head pullover, broken screws, warping oil-canning and buckling by using the Fascia Bit!

The 1/4" arbor fits standard drill bits.  Most commonly used in PVC and composite fascia board installations .  For use with: #8 316 Stainless Steel Composite Fascia Screws.


Easy and efficient. Use the fascia counterbore bit to predrill the oversized, counterbore holes into your fascia material. Refer to the spacing diagram in the Gallery, Installation tab.

  1. Starting at the upper left corner, position the first hole 2" from the upper and left edges (top left corner). Then continue predrilling holes every 24" on center, with the final hole positioned 2" from the right edge. Repeat this process, starting 2" from the bottom and left edges (bottom left corner), but place the second hole 12" from the first and then stagger predrill holes every 24" after that, with the final hole 2" from the bottom and right edges.
  2. Using a drill-driver motor with torsion setting adjusted to drive the screw flush with the board surface, install fascia screws into each hole. Do not overdrive or over tighten.
