The Certifix HCT2LS is a high-performance A4 stainless steel bi-metal screw designed for secure and reliable fastening in both aluminium and steel. Featuring a hardened carbon steel drill tip with a protective Ruspert coating for smooth installation and enhanced durability, this screw boasts a hexagon head and a reduced drill tip for exceptional pull-out strength. Its coarse thread geometry is ideal for light gauge materials (1.2mm - 3.5mm). Complete with a preassembled EPDM bonded washer for a weather-tight seal and increased pull-through resistance. Applications include fixing helping hand brackets, top hats, steel brackets, fire barrier clips, and more. Suitable for corrosive environments and can be powder coated for external panels.
