The SAMAC CSK Light Section Screw with Wings 5.5mm is a specialist fixing designed for fastening light-gauge steel sections to timber in a single, efficient operation. Commonly used in roofing, cladding, and metal framing applications, these screws allow installers to work faster while achieving a clean, flush finish. The integrated drill wings open the hole in the steel section before snapping off as the screw enters the timber, preventing thread damage and ensuring optimal holding power in the substrate. The countersunk (CSK) head allows the screw to sit flush with the surface, making it ideal for applications
