Kreg Deck Jig™ (KJDECKSYS20)

Create a better, more-beautiful deck with the Kreg® Deck Jig™. This concealed-fastening system works together with Kreg Deck Screws to allow you to install decking without visible fasteners, so all you see is the beauty of your decking instead of a bunch of screws. The Deck Jig features hardened-steel guides to drill precisely positioned pilot holes, and to guide Deck Screws to attach decking from the edge solidly and invisibly—whether you’re using solid-wood or composite deck boards.

The Deck Jig makes drilling the stepped pilot holes and driving screws easy in all situations thanks to three hardened-steel guides — one at 90° to the board edge, and two at opposing 45° angles — that allow easy access when working near walls, as well as when creating strong joints where boards butt together end to end. The stepped drill bit creates a perfectly positioned pocket hole and clearance hole for the Kreg Deck Screw, while a stop collar ensures prefect drilling depth.

After drilling, just drop a Kreg Deck Screw — an integral part of this concealed-fastening system — into the same guide, and then drive it with the included square-drive driver bit. It’s equipped with a stop collar, too, to ensure that the self-tapping, case-hardened screw gets driven to the perfect depth. The aggressive threads bite securely into the joist while the smooth upper shank and flat-bottom head work together to pull the deck board tightly into place.

The Deck Jig Concealed-Fastener System works with composite decking, as well as solid-wood decking such as cedar, hardwoods, and pressure-treated wood — kiln-dried after treatment (KDAT) recommended.
