Porous Concrete Screw 8 × 140 mm

The Porous Concrete Screw 8 × 140 mm is a high-strength fastening solution that eliminates the need for anchors, designed for secure fixation in aerated concrete. This screw allows for direct installation into structures without pre-drilling, thanks to its specially designed thread that engages directly with the material. This significantly saves time and labor costs during the installation process.

Manufactured from hardened carbon steel with a specialized coating, this screw ensures high mechanical strength and durability even in challenging conditions. It is suitable for use indoors and in partially damp environments, in accordance with EN 1995 (Eurocode 5) and EN ISO 12944-6 C4 durability class.
