Abstract: Different insert fittings (screws, plastic and metallic sockets, plastic and metallic cam fittings single and double) are widely used in ready-to-assemble cabinet furniture joints, connecting particleboard and MDF. The holding strength of insert fittings and the bending strength of the corresponding furniture corner joints constructed with the same fittings were studied. The insert fittings which are offered by four (4) manufacturers (Hettich, Häfele, Lama and one of no name) were studied. Research reported here indicated that bending strength values of furniture corner joints constructed with insert fittings strongly correlated to the face holding strength of the corresponding insert fittings (bending strength is almost equal to holding strength multiplied by 10). Based on these results, it is concluded that the bending strength value of a corner joint constructed with insert fitting could be sufficiently estimated by the measured holding strength value of the corresponding insert fitting.

Key words: insert fitting, holding strength, corner joint, bending strength, furniture.
