The CERTIFIX CFTSF2 4.9×24 TX20 BiMetal A2 Cleat Screw is a high-performance, specialised drilling screw designed for the direct and frictionless fastening of standing seam cleats onto metal substructures. This screw integrates a drilling process with the fastening solution, offering significant time and cost savings during installation on both aluminium and structural steel roof and façade components. The screw's design is optimized for standing seam systems. Its flat, washer countersunk head ensures a low-profile contact surface, guaranteeing both high contact pressure and a friction-free path for the standing seam sheets to slide over, accommodating thermal expansion without causing damage. The advanced SIT®20 drive provides wobble-free screwing, maximum power transmission, and compatibility with standard TX bits. Crucially, the inclusion of a locking serration prevents both overwinding during installation and inadvertent unscrewing over time, enhancing the fastener's longevity and security. The robust single start thread ensures a high load capacity, while the sharp drill tip handles simultaneous drilling into the substrate, making the CFTSF2 a professional, efficient, and reliable solution for fixing cleats, comb fillers, edge parts, and metal sheets. Positioning can also be corrected and dismantled without damaging the cleats.
