Timber engineering Timber frame construction with KonstruX ST © diyanadimitrova – stock.adobe.com Connections with fully threaded screws The KonstruX ST is a universal fully threaded screw for connecting timber frame elements such as posts and cross-beams. Measuring 6 mm in diameter, the KonstruX ST ZK is especially suitable for connecting slim timber frame elements grouped in service classes 1 and 2. Due to the special drill tip geometry, reduced edge and centre distances may be used. This enables use in smaller cross-sections. The reduced drill tip has no negative impact on the extraction resistance of the screw thread. The fine double thread behind the drill tip reduces the screw-in torque. Fully threaded screws are optimally used when they are loaded axially, i.e. in tension (or compression). Full-thread screws cannot reach their full potential if they are used for shearing only. Therefore, always try to position the screws in the direction of the force applied. If the force-axis angle (not to be confused with the axis-fibre angle) is between 0° and 45°, the bolts may be considered as purely tensioned. Proof of shearing is therefore not required. The connection is therefore much more stable with an inclined screw connection than with a screw connection at 90° to the force. KonstruX ST may be set independently of the fibre direction, i.e. also parallel to the fibre. The pull-out resistance remains between 45° and 90° mathematically equal. 220 Matching screw KonstruX ST: ZK, Ø 6,5 mm Assembly pliers: 80 – 195 mm Sinkable cylinder head Material: Steel hardened Surface coating: Electrogalvanised
