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.\n\nThe 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.","brand":"Certifix","offers":[{"title":"Default Title","offer_id":51192737923236,"sku":"11097","price":45.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0657\/4496\/1700\/files\/4_9x24_TX20_main.jpg?v=1764820940"},{"product_id":"certifix-cfssc2-bimetal-a2-4-5x24mm-countersunk-with-sit20-cleat-screw","title":"Certifix CFSSC2 BiMetal A2, 4.5x24mm Countersunk with SIT®20 cleat screw","description":"The Certifix CFSSC2 BiMetal A2, 4.5x24mm Countersunk with SIT®20 cleat screw is a specialized drilling solution designed for the chipless fixing of standing seam cleats to thin-walled sheet metal substructures under 1 mm. Built from high-quality A2 stainless steel bimetal with a blue zinc-plated finish and nickel strike, these screws are engineered specifically for roofing and façade construction. The unique thin sheet metal tip displaces material downwards rather than cutting it, which prevents sharp metal chips from damaging sensitive, non-breathable membranes. This displacement also creates more thread turns in the material, resulting in exceptionally high pull-out values even in very thin components.\n\nDesigned for speed and reliability, the CF-RP-T2-SSK features a double thread for fast screw-in times and a flat washer countersunk head that allows standing seam sheets to slide smoothly over the fastening point. Installation is made secure by the SIT® 20 drive and a specialized locking serration that provides both overtightening protection and permanent loosening resistance. This ensures that the screws do not work loose over time while still allowing for easy position corrections during the initial install without damaging the cleat.","brand":"Certifix","offers":[{"title":"Default Title","offer_id":51216761094308,"sku":"16898","price":69.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0657\/4496\/1700\/files\/05-SKDB25B020-0450241-1_G_0f81ec36.jpg?v=1769224706"},{"product_id":"certifix-cfts4-4-8-24-tx20-bibmtal-a4-countersunk-with-sit20-cleat-screw","title":"Certifix CFTS4 4.8×24 TX20 BiMetal A4, Countersunk with SIT20 cleat screw","description":"The Certifix CFTS4 4.8×24 TX20 BiMetal A4, Countersunk with SIT20 cleat screw standing seam clip screw is a specialized drilling solution designed for the chipless fixing of standing seam cleats to thin-walled sheet metal substructures under 1 mm.
