TITANIUM STEM BOLT M6 X 20MM TAPERED HEAD BLACK (EACH)
The Titanium Stem Bolt M6 x 20mm Tapered Head Black combines aerospace-grade strength, weight savings, and a sleek stealth finish to elevate your cockpit.
When fine-tuning your bicycle, every gram and every detail counts. The Titanium Stem Bolt M6 x 20mm Tapered Head Black is engineered for riders who refuse to compromise between high-end performance and a clean, understated aesthetic. Crafted from premium Grade 5 (6Al-4V) titanium alloy, this bolt provides the exceptional tensile strength required to keep your handlebars securely locked in place, while weighing roughly half as much as a conventional steel fastener. Whether you are racing cross-country, shedding weight from a road cockpit, or upgrading a custom build, this component delivers reliable clamping force under the most demanding riding conditions.
Beyond its impressive mechanical properties, this titanium stem bolt is completely immune to rust and atmospheric corrosion, ensuring your front end remains clean and structurally sound season after season. The deep black finish is applied using an advanced physical vapour deposition (PVD) process, providing a highly scratch-resistant surface that integrates seamlessly with modern matte or gloss black stems. The low-profile tapered head design sits flush in compatible stems for reduced wind resistance and a modern, factory-integrated look. Supplied individually, this bolt features a precision-machined standard Allen key drive that resists rounding out during high-torque installations. It is the perfect blend of structural integrity and subtle elegance for any discerning cyclist.
Key Features
Grade 5 Titanium Construction: Manufactured from aerospace-grade 6Al-4V titanium alloy, offering an incredible strength-to-weight ratio that easily outperforms standard steel hardware.
Corrosion Proof: Inherently resistant to rust, road salt, moisture, and sweat, ensuring the threads will not seize and the structural integrity will not degrade over time.
Premium Black PVD Finish: Features a durable, wear-resistant black coating that provides a high-end, stealthy look to seamlessly match modern bike cockpits.
Sleek Tapered Head: Engineered with a low-profile, tapered head design that drops cleanly into countersunk stem bolt holes for a flush and aerodynamic finish.
Precision Hex Drive: Engineered with a clean, standard Allen key head interface to prevent tool slippage and rounded heads during critical assembly.

✅ Why This IS For You
✅ The Weight Weenie: You are actively counting grams and looking to shave critical weight from your cockpit without sacrificing structural safety.
✅ The Stealth Builder: You prefer a clean, understated, all-black aesthetic over flashy oil-slick or raw silver components.
✅ Countersunk Stem Owners: Your premium stem features recessed or tapered bolt holes that require a flush-fitting fastener rather than a boxy standard head.
✅ All-Weather Commuters: You ride frequently in rain, mud, or coastal environments and want to permanently eliminate ugly, rusted bolt heads on your stem.
✅ Premium Parts Enthusiasts: You appreciate precision-machined, high-tensile fasteners that can handle repeated, accurate torque settings.
❌ Why This May NOT Be For You
❌ Standard Flat-Bore Stems: If your current stem features flat, non-countersunk bolt faces, a standard parallel-head bolt is required to distribute the clamping force correctly.
❌ Longer 25mm Bolt Users: Some beefier mountain bike stems require a longer 25mm thread depth; using a 20mm bolt on those setups will not provide enough thread engagement.
❌ Oversized M7 Stem Users: While M6 is highly common, some specific brands use M5 or M7 threads; you must check your manufacturer specifications first.
BFC PRO TIP
Titanium hardware behaves differently to steel. Because titanium is prone to "galling" (friction welding) when threaded into aluminium or other titanium parts, never install this bolt dry. Always apply a thin layer of high-quality anti-seize lubricant or a specialised bicycle grease to the threads and under the tapered seating face before loading it into your stem. When tightening, always use a calibrated torque wrench to bring it to the manufacturer's exact specification—this ensures a permanent hold without damaging your expensive carbon or alloy components!
