Special characteristicsDynaplus® construction screws have been developed for connecting wooden beams and load-bearing timber structuresThanks to the large TX drive, you have optimal power transfer from the (impact) screwdriver to the screw, allowing for easy processingWith their special drill tip featuring cross-sections and a cutting point, they can often be used without pre-drillingThe construction screw is a perfect alternative to the 'old-fashioned' coach screwConstruction screws are many times stronger and have a much higher pull-out valueThe washer head on the screws provides a large bearing surface and clamping range, making the screws capable of handling heavier loads and requiring fewer fastening points for a sturdy timber structureFrom 80 mm, the screws feature partial thread with a so-called 'spiral' that enhances the pulling effect in wood-to-wood connectionsThe 'spiral' pre-drills the screw hole slightly wider, which improves the pulling of the second piece of wood and minimizes the risk of splittingThe screws are made of hardened carbon steel and are super strongAn additional annealing treatment during the production process eliminates the risk of hydrogen embrittlement in the materialFor creating safe building structuresThanks to the large clamping range of the washer head, these screws can also be used for mounting soft sheet materials such as insulation material or wood wool cement boards.Technical dataDiameter {mm}: 8Length {mm}: 260Thread length {mm}: 100Thread type: Partial threadHead type: Washer headDrive: TX-40Drive type: TXDrive size: 40Drill tip type: Cutting point type-17|Cross-sections|Serrated threadHead diameter {mm}: 21Spiral: YesMaterial: Carbon steelSurface treatment: Electrolytically galvanizedSurface treatment color: BlueLubricant: GleitmoCE Standard: 14592
