The tool works as a helping hand when the screw needs to be installed

  • What board width does the Deck Pro tool work for?
    Deck Pro fits all standard board widths on the market, the same tool fits boards from 85-150 mm in width. For boards over 150 mm in width, 3 attachment points are generally recommended, where we instead recommend a top-mounted solution.
  • What board thicknesses can be used when mounting Deck Pro screws?
    Deck Pro screws have the dimension 4.5x60 and fit all boards from 18-34 mm in thickness. However, it may not be installed in hardwood or other types of exotic wood-types.
  • Can I use Deck Pro on hardwood?
    No, Deck Pro is recommended for most types of wood, but not for hard wood. When building decks with hard wood, you should instead use one of our top-mounted decking screws with a thickness of at least 5 mm, such as Deck+ HE or SPUN+ SUH.
  • How does hidden montage work? Can you see the screw holes?
    When mounting your screws with the Deck Pro tool, the placement of the screw is optimized to be as far down on the edge as possible, without compromising with the strength and durability of the installation. If you look closely at an individually mounted screw you will be able to get a glimpse of the screw hole. However, if you look at the decking from a normal distance the impression is that the screws are "invisible".
  • Is there a risk of water seeping into the wood where the screws are mounted?
    The Deck Pro screw is developed with a cylindrical head that closes the hole during installation, this will prevent water from penetrating into the wood.
  • How do I mount in angles where the tool cannot be used?
    The screw has a reduced drill tip that provides a quick start in tricky angles, this means that the screw can be installed without the tool if needed.
  • How big is the distance between the boards?
    When buying the Deck Pro tool, distance blocks are included that allows the distance between the boards to be adjusted, from 3 mm up to 7.5 mm. The tool comes pre-mounted with a 6 mm distance in accordance with building standards but can easily be changed if a different distance is desired.
  • Which screws fits the Deck Pro tool?
    The Deck Pro is a system solution where screws and bits that are specially developed with the tool. Generally, other hidden screws on the market have too large heads and will therefore not fit our tool. However, our Deck Pro screw works well with other tools on the market as well.
  • How is the Deck Pro different from other tools on the market?
    The Deck Pro tool has a unique adjustment function which means that one and the same tool can be easily adapted to all common deck widths on the market, from 85-150 mm. Other tools on the market today require two different tools, one for thinner and one for wider boards. The Deck pro handle is developed with a focus on optimization and ergonomics and can withstand up to 100 kg of direct load. Many also feel that the Deck Pro is more stable and stands more stable against the board.
  • Why is the minimum distance 3 mm?
    General building standards recommend 6 mm distance between each decking board, taking into account that the wood can expand or contract up to 5 mm depending on current prevailing humidity. To avoid larger gaps in the wood when mounting in damp conditions, Deck Pro is possible to adapt into a minimum distance of 3 mm. However, it is important to remember that smaller distances between the boards lead to an increased risk of boards colliding. We always recommend to follow national building standards.
  • How do you mount the boards against the wall?
    For a hidden assembly of a board that lies against the wall there is a smart little trick. Pre-assemble the board onto a shorter support beam using the Deck Pro tool. Further, insert the pre-assembled board against the wall and then attach the support beam to the primary beam.
