Tackling the challenges of timber
Timber lends itself to all manner of construction, from interiors to exteriors, structural work to intricate design and finishes, decks and stairs, and a huge spectrum of environmental and climate variations. Using the right materials and tools for a quality fit and finish is imperative to ensure longevity, security and strength among other considerations. Torque looks at some of the screws and tools ready to take on any timber engineering challenge, including offerings from Heco-Schrauben & REISSER
Heco-Schrauben > HECO-TOPIX-plus one that does it all
The innovative HECO-TOPIX-plus wood screw brings together the best product properties from four HECO screw families and is an all-rounder for almost all applications. In 2022, HECO added to its range with further versions in additional drive sizes.
Since 2021, the HECO-TOPIX-plus wood screw has fully replaced the four screw families HECO-UNIX-plus, HECO-UNIX-top, HECO-TOPIX and HECO-FIX-plus, combining all their user benefits in a single wood screw type. It has an optimised thread pitch which has been adapted to the thread length (PerfectPitch), and the full-threaded screw version can pull components together (MagicClose). The stainless steel version of the innovative wood screw is particularly straightforward to work with, as its screw head is a perfect fit in the bit where it is held mechanically without a magnet (GripFit). As a result, it can be positioned and inserted single handed. With these properties, the HECO-TOPIX-plus is suitable for a wide range of applications – from furniture and terrace construction to structural timber work.

Additions to the HECO-Drive and T-Drive ranges
For straightforward, practical usage, both HD bits and T-Drive bits in the HECO range are compatible with HD screws and T-Drive screws. The drive size range now features additional T-25 screws with a diameter of 4.5, 5 and 6mm with countersunk and flange head. HD-30 screws are now available with a diameter of 5mm too. Allowing users to have more options when it comes to the drive size.
REISSER > DNS®Plus The fast universal screw for wood applications
With the DNS Plus wood screw, REISSER-Schraubentechnik GmbH offers a new means for fast and secure screw fastening with a double thread or coarse thread and the SIT® drive.
The newly approved REISSER DNS Plus wood screw with its SIT drive guarantees fast drive finding, wobble-free screw fastening and maximum power transmission without the risk of overtightening.
Special requirements for product quality and processing efficiency are fully satisfied. DNS Plus is included in the REISSER design software and provides tested and monitored quality through the existing ETA approval, as well as CE marking as a construction product.
Two models are available: the REISSER DNS Plus wood screw (from 3.0mm) and the REISSER DNS Plus wood construction screw (from 5.0mm). The area of application of the DNS Plus wood screw is interior fittings, as well as handicraft and industrial furniture construction. The DNS Plus wood construction screw is also used for interior fittings and in wood construction.

The REISSER DNS Plus can be processed with a standard Bit TX without any problems. Due to the flat countersunk head with universal milling pockets, the DNS Plus screw can be used for wood screw connections and fitting assembly since no damage is caused to the metal. Indoor furniture fittings can be securely fastened, as can wood-based panels on wooden substructures for interior fittings and in wooden element construction. It can also be screwed to wooden structures that are subject to static loads and require approval and be used to insulate overhead rafters.
The existing double thread or coarse thread makes a quick screw connection possible. With the double thread of the DNS wood screw, two threads, one inside the other, save up to 50% time during screw fastening in comparison with conventional chipboard screws. Thanks to smaller distances due to the two threads, stability in the wood increases.
On the other hand, with the coarse thread of the DNS wood construction screw, the high thread pitch ensures a high screw-fastening speed and a reduced/decreased splitting effect. The additional end mill of the DNS wood construction screw widens the screw channel in the component being fastened, which in turn reduces stress, especially in the case of long screws.
The SPI tip enables a precise and immediate screwing start thanks to the needle tip. In addition, the thread at the tip significantly minimises the splitting effect.
An electric or pneumatic screwdriver is required for processing. Ideally, this is carried out with direct screw fastening without pre-drilling and pre-sinking, depending on the processing situation and the condition of the wood.
