Abstract: In this paper; it was carried out to determine the withdrawal strength of some screws and nails of WFB, picea and oriental beech that are using at furniture product. For this reason, it was applied the withdrawal strength of experimental specimens with different screws and nails. According to the result of experiments, it was obtained the highest withdrawal strength result of oriental beech whose face perpendicular to screw 20x35 (17,670 N/mm^2). It was obtained the highest withdrawal strength result of picea whose face parellel to nails such as 16x30 (6,920 N/mm^2).
