Lateral holding strength of wooden dowel, screw and ready-to-assemble joints (RTA joints) constructed of Medium Density Fiberboard (MDF)

In the present study the strength of different kinds of wooden dowels, screws, and ready-to-assemble joints (RTA joints) used in medium density fiberboards (MDF) were assessed and compared for their lateral shear strength. The T-form specimens (20 cm × 8 cm) were comprised of two MDF parts in compli...
