Screw for drywall SN 4.2x22mm Vidifloor KNAUF

The gypsum fiberboard screw from the SN Vidifloor series from the world leader KNAUF is a highly specialized, top-class fastener designed for dry construction and dry floor construction. This model is specially designed for secure and mechanical fixing and tightening of gypsum fiberboard floor panels from the Knauf Brio, Brio WF and Vidifloor series. The main function of the screw is to exert powerful and uniform pressure to keep the panels tightly adhered to each other during the gluing process, ensuring that the floor adhesive will bond in the most efficient and monolithic way possible.

The specific geometry of the SN screws includes an optimized milling head with special ribs that allow the fastener to sink and sink completely smoothly into the solid structure of the gypsum fiber board, without cracking or delamination of the material. Made of high-quality steel with an anti-corrosion phosphate coating, the screw offers excellent protection against construction moisture and long-term stability. The compact and precisely calculated length of 22 mm is critically important when installing floor systems, as it ensures a firm fixation of the assembly, without the risk of drilling the subfloor layer or unintentionally damaging underfloor heating pipes and hidden installations.

Purpose:

• Mechanical fixing and tightening of Knauf Brio, Brio WF and Vidifloor gypsum fiber floorboards
• Providing the necessary pressure during the curing of the adhesive when assembling dry floors
• Construction of floor systems in dry and wet rooms with dry construction
• Creating stable and monolithic floor connections without lifting the finish coating

Main advantages:

• Phosphated coating for reliable and long-lasting protection against corrosion and the chemical effects of floor adhesives
• Special head with countersinking ribs that sinks perfectly below the surface level for a completely flat floor
• Precisely calculated length of 22 mm for complete safety of hidden underfloor installations and pipes
• Optimized thread for hard materials, providing maximum clamping and pulling force between panels
• Professional pack of 500 pieces, ideally dosed for medium-volume interior flooring projects
