Delta Protekt KL 100 coated steel
Self-drilling roofing screws are the ideal fastening solution when it comes to attaching insulation or fixing roofing membranes to structures made of sheet steel, aluminum sheet, wood or wood-based materials – whether it is a new construction or renovation.
The self-tapping screws for flat roofs have a Delta Protekt KL 100 anti-corrosion coating, which not only enhances corrosion resistance but also withstands thread abrasion during repeated use.
Self-tapping screws for flat roofs are capable of drilling steel profile sheets up to 2 mm thick.
The countersunk head of the roofing screws has a Phillips and star (Torx) slot.
