Use: coarse thread screws for quick and secure attachment of plasterboard to a wooden substructure. Suitable for solid wood or wood-based materials without pre-drilling. Thanks to the coarse thread, the drywall screw pulls particularly quickly into the solid wood. The trumpet head ensures a secure hold and allows a flush finish without damaging the cardboard layer of the plasterboard. The black phosphating provides temporary corrosion protection and ensures good adhesion of filler. The chemical reaction with plaster and the possible appearance of rust stains is prevented. The H force attack provides optimal power transmission and secure grip during processing.
