Black Stainless Steel Decking & Cladding Screws Tiger-TX black stainless steel multi-purpose screws are superb for timber projects where appearance matters as much as performance does. Manufactured using A2 stainless steel and finished with the amazing CB10 black oxide process, they combine engineered high-performance screws with a clean consistent black finish - CB10 screws last for years and years in outdoor exposed areas. • Built for Outdoor Timber Standard decking screws leave behind the tell-tale silver glint of exposed steel across every board - especially visible as the timber weathers and darkens. Tiger-TX Black CB10-coated screws blend into the decking surface, maintaining a uniform black finish - whether you're working with hardwood, softwood, cedar cladding or pressure-treated timber. The countersunk head, with its flushing ribs underneath, sits flat with the board surface and pulls cleanly through each board without the need for pre-drilling (in most applications). • Twin-Cut Slit Slash Point The twin-cut tip features two cutting edges that slice cleanly into timber rather than forcing fibres apart, ensuring rapid and consistent pick-up every time you drive a screw in. This minimises the risk of splitting, even close to board ends. It also means faster, cleaner installation across large areas of decking & cladding boards. • Helix Shank The helix shank clears debris from the hole as the screw drives in, improving clamping force between boards and joists - reducing the tendency for the screw to ride up during installation. The result is a tighter, more secure fixing with better long-term holding strength across a wide range of timber types. • Six Lobe Torx Drive The six lobe Torx drive is engineered to eliminate cam-out entirely. I hear say "what the heck it cam-out". Well Cam-out is when a screwdriver or drive bit slips out of the head of a screw while tightening or loosening the screw, resulting in you turning the air blue. It happens because the driving tool's angled edges ride up the angled surfaces of the screw recess, and slips out often damaging the head. A torx head screw pretty much eliminates this, torx bits rarely slip out when driving in a fastener.
