Kreg Tool KJDECKSYS - KREG Deck Jig Concealed Fastening System

Whether you’re building a new deck or refinishing an old one, you want to do the job right. With the Kreg Deck Jig™ – and a few simple tools you already own – you can create a beautiful and functional deck surface, completely free of exposed fasteners and painful splinters! Traditional concealed-decking systems utilize awkward steel fasteners or thin plastic clips to hold your deck boards in place. The Kreg Deck Jig™ utilizes a more straight forward approach, creating an incredibly strong wood-to-wood bond through precisely placed self-tapping screws.

Standard Deck vs. Kreg Deck
Get the deck you want, without any unsightly exposed nails or screws. The Deck Jig’s specialized self tapping screws are driven at a precise angle into the edge of your deck boards so they stay hidden from view. Where seasonal changes might force traditional fasteners out of place with time, Kreg screws stay protected safely below the surface, for a longer-lasting deck. By coupling the Kreg Deck Jig™ with composite decking, you’ll get a deck free of cracks, splinters, and “pop-out” fasteners.

Drill. Drive. Done!
Securing a deck board with the Kreg Deck Jig™ takes only 3 simple steps. First you drill holes into the edge of your deck board using the specialized stepped bit, guided by the jig’s hardened steel drill guides. Next, you drive the specialized self-tapping deck screws through the same drill guides and into the joist as the depth collar precisely controls the depth. That’s it, you’re done! You’ve just created an incredibly strong and sturdy joint with no visible fastener.

Works with a wide variety of decking materials.
For the best results, we recommend composite deck boards which prevent shrinking/swelling/splitting. Select a solid composite material with no machined grooves. Also works great with native softwoods such as Redwood and Cedar, along with certain Tropical Hardwoods like Ipe, Red Balau, and Ironwood. Works exclusively with 4/4 to 5/4 (3/4" to 1-1/8") stock. Not designed for use with 2x material including 2x4's, 2x6s, 2x8s, etc.

Deck Screws
Kreg Deck Screws were designed specifically for use with the Kreg Deck Jig™, although they can also be used as simple face-screws for a variety of outdoor projects. All Kreg Deck screws feature a KTX #1 Square Drive to reduce cam-out, a flat-bottom head which resists splitting, and a self-tapping tip which drills its own hole as it’s driven.

Deck Screws are available in two weather resistant finishes; Protec-Kote™ and Stainless. Protec-Kote™ screws feature three anti-corrosion layers which protect against rusting in a wide variety of decking applications. A good choice for a wide variety of decking applications, including ACQ treated lumber. For even more protection, choose Stainless. Kreg Stainless screws provide the best protection against corrosion in the long-term.
