The Invisible Plug Connection Screw

The Invisible Plug Connection Screws are suitable for connections between wood and wood, wood and metal, and wood and concrete, which are not visible from either side after assembly. The large versions of the IPC screws listed in the description are suitable as special fasteners for overlaid stair treads. First, a blind hole is drilled into the "base material," for which the appropriate depth and diameter are chosen depending on the application and material. A plastic sleeve is then driven into this hole, into which a center punch can be inserted for marking the opposite side. At the marked point of the counterpart, the plug connection screw is now screwed in, which can then be pressed into the sleeve of the base piece like a snap button. This saves the user, whether a hobbyist or a professional craftsman, a lot of work, achieves high precision, and creates a secure, load-bearing connection of the parts.
