Black Stainless Steel

Our black stainless steel decking and cladding screws are engineered specifically for exterior timber applications where visual appearance is just as important as structural performance. Manufactured from premium A2 stainless steel and finished using the advanced Carbolts CB10 black oxide process, these screws combine the strength and reliability of a high-performance decking screw with a deep, uniform black finish designed to withstand decades of outdoor exposure. Built for Exterior Timber Projects Traditional decking screws often leave a visible silver reflection across the finished surface, particularly as timber ages and darkens over time. Our CB10 black stainless screws virtually disappear into the timber, creating a clean, uninterrupted appearance across decking, cladding, fencing, pergolas and architectural timber features. The countersunk head incorporates precision milling ribs beneath the head, allowing the screw to seat flush with the timber surface while reducing splitting and eliminating the need for pre-drilling in most softwood and many hardwood applications. Twin-Cut Slit Point for Faster Installation The precision-engineered twin-cut point features two cutting edges that slice through timber fibres rather than forcing them apart. Benefits include: Faster pick-up and engagement. Reduced driving torque. Lower risk of splitting, even near board ends. Cleaner installation in both softwood and hardwood. Improved productivity on large decking and cladding projects. Tiger-TX Helix Shank The Tiger-TX helix shank removes timber debris as the screw advances, reducing friction and improving overall installation performance. This innovative shank design: Increases clamping force between boards and substructure. Prevents the screw from "riding up" during installation. Produces tighter, more secure fixings. Enhances long-term holding power across a wide range of timber species. Six-Lobe Torx Drive | Zero Cam-Out Unlike Phillips or Pozidriv drives, which are designed to release under excessive torque, the six-lobe Torx drive transfers force directly into rotational movement. The result is: No cam-out. No damaged screw heads. Greater torque transfer. Faster installation. Reduced driver bit wear. A cleaner finished appearance. For professional installers driving hundreds or thousands of screws, the Torx drive dramatically improves efficiency while maintaining consistent installation quality. Why Choose CB10 Black Oxide? Many black screws rely on painted or polymer-coated finishes that can chip, peel or wear away during installation. Damage typically occurs around the drive recess, threads and point, exposing bright metal beneath. CB10 is fundamentally different. Rather than applying a surface coating, the CB10 process chemically converts the outer layer of the stainless steel into a permanent black oxide finish. Because the finish becomes part of the metal itself, it cannot chip, flake or peel. Advantages of CB10 include: Permanent black finish. No coating delamination. Uniform colour across the head, recess, shank, thread and point. Superior appearance throughout the life of the installation. Excellent compatibility with modern architectural timber designs. The Ideal Screw for Shou Sugi Ban® and Charred Timber Cladding Charred timber cladding demands a fixing that complements its distinctive appearance. Conventional stainless steel fixings often stand out sharply against the deep black surface, disrupting the visual continuity of the façade. Tiger-TX Black Stainless Screws provide a seamless solution. The permanent CB10 black oxide finish closely matches the rich tones of Shou Sugi Ban® and other charred timber systems, allowing the fixings to blend naturally into the cladding face. Because the CB10 finish is chemically bonded to the A2 stainless steel substrate rather than applied as a surface coating, it will not chip or flake when driven into dense, resinous or heavily charred timber. The result is a discreet, flush fixing that works with the material rather than against it. For architects, contractors and self-builders seeking a cohesive design, Tiger-TX screws deliver a truly integrated black-on-black finish from board face to fixing point.
