Cross-laminated timber and self-tapping wooden screws: the ideal partners for solid timber construction

Adequately long and powerful connections are required to achieve true load transfer between these slabs (e.g. for floor-to-floor and wall-to-wall connections). Self-tapping screws play a crucial role in this regard and are preferably used due to their easy installation, reasonable length for long penetrations and their extraordinary strength-to-ductility ratio compared to dry wall screws. A distinction is made here between partial and full-thread screws, with the former being used more for installation purposes and lateral loads and the latter optimised for axial loads.

For this reason, Eurotec has geometrically and materially developed the ETA and ICC-certified screws (Paneltwistec, SawTec, KonstruX) – with sizes of up to 10 x 1000 mm with a maximum pull-out resistance and a yield moment of 12.2 kN and 70 Nm – for high-strength and low-cost connections of solid wood elements.

Always a strong connection

Due to growing challenges and the rapid development of wood construction materials, Eurotec continues to work intensively on targeted unique solutions for highly stressed wood connections.
