Tests were carried out in order to determine the bending strength with compression and tension force with and without glue in addition to screws on furniture corner joints in a construction case. The specimens were prepared with particleboard and medium density fiberboard (MDF) surfaced with a synthetic resin sheet. In the connection, two types of screws which have dimensions of 4/50 mm and 5/60 mm were used. For the glued joints, polyurethane Desmodur-VTKA adhesive was used. As a result of these tests it has been determined that the joints with glue are better than the ones without glue and the strength of fiberboard is better than particleboard.
