Such devices may be useful, for instance, when assembling a frame for kitchen cupboards or drawers, and in many other products, typically when the end user assembles a product in his or her home without professional assistance. In many cases, different e.g. laminated board pieces are to be assembled, often by attaching one edge of one board piece to a flat surface of another. An assembling facilitating device may then consist of a wooden plug that is fitted into a hole in the surface of one piece. The plug length may then be twice the depth of the hole, such that one half of the wooden plug extends from the hole. The extending half may then be inserted into a corresponding hole the other piece when the pieces are fitted together. A number of such plugs may be used. This may not be enough to assemble the pieces, but keeps the pieces correctly aligned when, for instance, screws are applied to keep the pieces together. Moreover, the wooden plug offers some stability by preventing mutual movement between the pieces in a direction that is perpendicular to the plug axis.
One problem with such plugs is that they may be difficult to insert. Tolerances are important, as too thin plugs tend to fall out of the holes and too wide plugs may break the board piece when forced into the hole.
