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 prevent the nails from turning 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 dowel, there is no pressure force, which prevents the plaster from falling off or damaging the stone slab. The modeled wrapper around the nail neck prevents too deep mounting when mounting the dowel. 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 prevents the plug from slipping 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.
