We make every effort to ensure that the products delivered to our contractors are safe and adapted to specific tasks. Installation method Before installation, identify the substrate, its thickness, and environmental conditions (expressed in terms of corrosivity), and then select screws that meet the above criteria. Select the correct screw type, length, and drilling capacity, which depends on the sum of the thicknesses of the connected elements. The drilling capacity for each screw is specified in the dedicated Technical Data Sheet and in the PN-EN standard and refers to the sum of the thicknesses of the connected elements. Set the optimal speed when screwing in; too high speeds can cause drill bits to burn and prevent proper fastening. Screw installation should always be carried out perpendicular to the substrate surface. KLIMAS screws - the most common choice of professionals *measuring tape is not included in the sale
