Piilukiinnityksiä

Piilukiinnityksiä are a type of fastening system used in construction and manufacturing, primarily for wood-based materials. The term "piilukiinnitys" translates directly from Finnish as "hidden fastening." The core principle behind these systems is to conceal the fasteners, such as screws or nails, from the visible surface of the material. This is achieved by embedding the fastening points in such a way that they are not readily apparent after installation.

There are several methods employed for piilukiinnityksiä. One common technique involves using specialized clips or brackets that attach to the edge of one piece of material and then engage with a corresponding groove or slot in the adjacent piece. This creates a secure joint where the fasteners are entirely hidden from view. Another approach involves pre-drilling angled holes or using specific tools to drive fasteners at an angle, so they enter the adjoining material without penetrating its visible face. These methods are often employed in applications where aesthetics are important, such as in decking, cladding, cabinetry, and furniture making, to achieve a clean and seamless appearance. The effectiveness of piilukiinnityksiä relies on precise manufacturing of both the materials and the fasteners, as well as careful installation.
