Screws from carbon steel: Screw d = 3,0 mm: 2,7 kN Screw d = 3,5 mm: 3,7 kN Screw d = 4,0 mm: 4,3 kN Screw d = 4,5 mm: 5,5 kN Screw d = 5,0 mm: 6,8 kN Screw d = 6,0 mm: 10,7 kN Screw d = 8,0 mm: 19,1 kN Screw d = 10,0 mm: 29,8 kN Screw d = 12,0 mm: 32,7 kNScrews from stainless steel: Screw d = 3,0 mm: 1,6 kN Screw d = 3,5 mm: 2,1 kN Screw d = 4,0 mm: 2,8 kN Screw d = 4,5 mm: 3,5 kN Screw d = 5,0 mm: 4,3 kN Screw d = 6,0 mm: 6,2 kN Screw d = 8,0 mm: 13,0 kNFor screws used in combination with steel plates, the tear- off capacity of the screw head should be greater than the tensile strength of the screw.The thickness of the insulation ranges up to 400 mm. The rafter insulation must be placed on top of solid timber or glued laminated timber rafters or cross-laminated timber members and be fixed by battens placed parallel to the rafters or by wood-based panels on top of the insulation layer. The insulation of vertical facades is also covered by the rules given here.
