The main goal of this study was to determine the effect of wood species and loose tenon length on the withdrawal force capacity of mortise and loose tenon (M<) T-type furniture joints. The specimens were manufactured from oak (Quercus alba), beech (Fagus orientalis L.), poplar (Populus deltoides), sycamore (Platanus orientalis), fir (Abies alba), and white walnut (Juglans cinerea), and the tenon species selected was oriental beech (Fagus orientalis L.). The length of the tenon was determined on the basis of the length glued into the horizontal member of the joint. The lengths in the present study were 10, 20, and 30 mm. It was found that joints manufactured from beech had the highest withdrawal force capacity; this trait was lowest in joints made from the light wood of poplar and fir. The glued-in length of the tenon exerted a significant influence on the withdrawal force capacity of the joints. The greatest withdrawal force capacity increment of M< T-type joints was obtained when the tenon length changed from 10 to 20 mm.
