In the presented research small-scale specimens consisting of cold-formed steel (CFS) stud segments attached to woodbased boards were tested to identify the response of fasteners under push-out (shear), pull-out (tension) and rotational actions. The experimental programme was designed to investigate the effects of key design parameters, namely the thicknesses of the CFS studs and the wood-based boards, the board material (OSB vs. plywood), the presence of washers, and the screw spacing. A range of failure modes was encountered, including screw tilting, bearing failure in the boards and pull-through. The key results of the experiments are summarized herein, aiming to provide a better understanding of the behaviour of the board-to-CFS fastenings, as well as make data available for further analytical or numerical research.
