• APPLICATION

    Hidden fastening for structural screws in framing lumber, pergolas, and exposed beams. Plugs are made from actual lumber to match perfectly. Installation is a four-step process utilizing a setting tool, screws, glue and plugs. All components must be used together as instructed to ensure proper function.

    • Plugs are for 2″ nominal (or greater) lumber
    • Kit packaging includes screws, glue nozzle, and plugs (tools sold separately)
    • Smart-Bit Depth Setting Collar prevents damage to wood surface
    • Screws feature either Type 17 auger tip (316 Stainless) or Tri-Forge™ (Black Exterior Grade Coating) for faster, easier insertion and to help prevent splitting

  • INSTALLATION

    Follow all lumber manufacturer instructions, including specifications for screw spacing, and edge/end distances.

    • Align the underside of the Depth Setting Collar with the second groove
      on the 22mm Forstner bit and tighten the set screw until the Depth
      Setting Collar is firmly in place.
    • Pre-drill with the Forstner bit in a straight and steady fashion until the
      Depth Setting Collar stops spinning. Remove any debris from the hole.
    • Drive the appropriate structural screw so that it is fully seated in
      the hole (Do not overdrive).
    • Apply glue to the hole. Attach the Glue Nozzle to the glue bottle.
      Start with slit of the glue nozzle aligned against the side wall of the hole.
      Gently squeeze the bottle and run the nozzle around the side wall of
      hole until it is all coated.
    • Insert a wood plug into the hole and tap with a smooth, large-faced
      hammer until the plug is flush with the lumber.
