Best used for
- 1Residential Ipe or Cumaru poolside decks where a smooth, fastener-free surface is required for barefoot comfort.
- 2Rooftop deck installations using Garapa or Tigerwood where consistent 5/32-inch spacing is necessary to manage drainage and moisture.
- 3Commercial boardwalks and public spaces using Massaranduba or Red Balau that require a high-strength, low-profile fastening solution.
- 4High-end fencing or siding applications where a uniform gap and hidden hardware are essential for modern aesthetics.
Pro tips for dense hardwoods
- Even with self-drilling screws, always pre-drill a pilot hole at a 45-degree angle through the hardwood board to prevent splitting near the fastener.
- Apply a small bead of high-quality exterior construction adhesive to each joist to assist the clips in preventing board rotation and movement over time.
- Ensure all tropical hardwood boards are properly acclimated to the local environment on-site for at least 7-14 days before installation to minimize post-install shrinkage.
- Use a 1/8-inch drill bit for pilot holes to ensure the stainless steel screws drive cleanly without excessive torque stress.

Why Choose Hidden Fasteners?
How Hidden Fasteners Work on Hardwood Decks
Pre-Groove the Boards
Hidden fasteners require a slot machined into the edge of each board. Most boards from Ipe Woods USA ship pre-grooved, or you can route the slot on-site with a 1/8″ slotting cutter.
Set the First Board
Secure your starter board to the joist with a face screw near the house-side edge. This first board anchors the rest of the field and will be covered by trim.
Clip, Screw, Slide
Insert the clip into the board groove, drive the supplied screw through the clip into the joist at roughly 45°, then slide the next board onto the exposed clip tab. The built-in spacer legs set the gap automatically.
Repeat Across the Deck
Continue across the deck, one board at a time. Each clip grips the outgoing board while spacing the incoming one — no measuring or shimming needed.
Pro Tip from Our Deck Specialists
In hot weather, tighten clips snugly but not crushing-tight. Exotic hardwoods expand and contract with moisture changes, and the clip must allow sideways movement to prevent buckling.
