Due to the material properties, it is strongly recommended to pre-drill the mounting part (screw diameter + 0.5–1 mm). Due to the varying bulk densities and moisture content, even in coniferous woods, the substrate must in most cases be pre-drilled with a 3 mm diameter drill bit over the entire length of the threaded shank. If in doubt, we recommend carrying out preliminary tests
