Innovative multi-purpose dowels suitable for attaching medium-heavy loads to all materials. The tip of the dowel has a notch that improves the penetrating force when drilling. Thanks to the new alternative system of beveled slots, the dowel bends in an empty space and adapts perfectly to any type of construction material. Two protruding coils effectively fasten the dowel to the wall and allow the nails to rotate when drilling. Two pairs of specially designed edges protect the dowel from turning, ensuring mounting and firm locking from turning. Thanks to the appropriate construction of the type, there is no pressure force, which leads to falling off of the plaster or damage to the stone slabs. The modeled shell around the nail neck prevents pre-deep mounting during mounting type. Specially designed wings and protrusions on the dowel prevent the dowel from turning when fixing the hook screw. Solid plug, for use with plywood screws, wood screws and spacer screws. The rim allows the plug to slide into the drilling hole, but also allows installation through pressure. Advantages: Anti-rotation wings prevent the plug from turning in the drilling hole; Expansion-free plug helps prevent damage to tiles and plaster; Plug geometry offers high load-bearing capacity in solid and semi-rigid building materials.
