Fix robust Gyproc Habito linings the easy way. 50mm British Gypsum High Performance Screws are designed to easily penetrate Gyproc Habito's strong core for trouble-free fixing. The screws have a lipped countersunk cross head design so that you can drive them in quickly and neatly with an impact driver. This leaves you with a perfect finish that's free from paper burring or bulging. Use our 50mm screws to fix boards up to 40mm thick to standard gauge metal studs, or up to 25mm thick to timber framing.
