What is Pregrooved (Pre-Grooved) Decking?
Pregrooved decking boards are milled with a groove along both edges of the board. That groove is designed to accept hidden deck fastener clips, allowing boards to be installed without face screws. The result is a cleaner finished look and a faster install compared to traditional top-fastened decking.
Pregrooved boards are commonly used for hardwood decking installations because they provide a premium appearance and help reduce common issues caused by face fasteningâlike surface checking around fastener heads and visible hardware.Learn about hidden fastener systems or view full installation guide.

How Pregrooved Decking Works with Hidden Fasteners
Hidden fastener clip systems are designed to sit in the groove along each board edge. Learn more about comparing hidden fastener options or use our decking calculators to estimate materials needed.
Typical Installation Sequence:
- Fastener clips are inserted into the groove and screwed down into the joist
- Each board locks into the clips, creating uniform spacing
- The next board engages the same clip system, continuing the pattern
This creates a clean deck surface with no hardware on the board face. If you prefer traditional face fastening, explore our eased-edge decking boards.
Compatible Hidden Fastener Systems
Pregrooved decking is compatible with most hidden fastener systems designed for grooved boards. Common clip systems include:
- Ipe ClipÂŽ style systems
- Tiger ClawÂŽ grooved board clips
- DeckwiseÂŽ grooved decking fasteners
- Similar clip systems built for edge-grooved boards
Our Recommended Fastener: Ipe ClipÂŽ
We sell and recommend Ipe ClipÂŽ hidden fasteners for pregrooved hardwood decking. These clips are specifically designed for dense tropical hardwoods and provide superior holding power with easy installation.

Installation Notes & Best Practices
Always follow local building codes (ICC) and consult the National Design Specification (NDS) for structural requirements.
Joist Spacing & Substructure
- ⢠Use a flat, properly supported substructure
- ⢠Joist spacing is commonly 16" on center
- ⢠Ensure adequate ventilation beneath the deck
Fasteners
- ⢠For dense hardwood decking, stainless steel fasteners are strongly recommended
- ⢠Use clip systems designed specifically for grooved hardwood decking
Natural Wood Movement
- ⢠Like all wood decking, pregrooved decking will expand and contract with seasonal moisture changes
- ⢠Proper spacing, airflow, and fastening technique are critical to long-term performance
Cut Ends
- ⢠Seal cut ends (especially hardwoods) to reduce end checking and improve durability
