Titanium Bolt M10x10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90mm Flying Saucer Torx T50 Head Screw for Motorcycle Bicycle Car, Pitch 1.25mm, by Tianswer

Aerospace-grade Ti-6Al-4V Grade 5 titanium M10×1.25mm fine pitch flying saucer (low-profile domed flange) bolts with high-torque Torx T50 drive, engineered for motorcycle radial brake calipers, suspension pivots, and automotive chassis bracing.

Flying Saucer Low-Profile Architecture & 18mm Load Flange

Featuring a distinct “Flying Saucer” (UFO-profile domed flange) design, this heavy-duty M10 fastener combines a massive 18.0mm load-distributing flange diameter with a compact 7.0mm low head height. The wide, integrated flange serves as an oversized structural washer, evenly distributing high clamping preloads across aluminum brake caliper mounts and suspension ears without digging into or galling recipient mounting surfaces.

M10×1.25mm Metric Fine Pitch Advantage

While general industrial fasteners use coarse 1.5mm pitch, high-performance motorcycle brake calipers and automotive chassis systems rely on M10×1.25mm metric fine threading. The finer thread pitch provides a larger minor core diameter (increasing tensile and shear strength by ~10%), finer clamping load adjustment per degree of rotation, and superior resistance to harmonic vibration loosening under severe track conditions.

Torx T50 Drive & Cam-Out Elimination

Standard internal hex (Allen) drive sockets on M10 hardware frequently strip or round off when subjected to recommended caliper torques of 40+ N·m. The precision-machined 6-lobe Torx T50 internal drive provides 100% radial contact and true tangential torque delivery. It completely eliminates cam-out and tool slippage, allowing confident, repetitive servicing with no fastener damage.

Threading Profile & Structural Shear Strength

For lengths 30mm and under, bolts are fully threaded. For lengths exceeding 30mm, the bolt incorporates a smooth, unthreaded shank with a standardized ~30mm thread engagement. This unthreaded shank aligns with critical shear planes between the caliper bracket and fork stanchion, maximizing joint shear fatigue resistance.

Key Applications

• Motorcycle Radial Brake Calipers: Brembo (M4, M50, Stylema, GP4-RX, P4), Tokico, Nissin, and Formula calipers requiring high-strength M10×1.25mm mounting bolts.
• Chassis & Suspension Mounting: Triple tree pinch clamps, rear shock upper/lower mounting eyes, footpeg bracket pivots, subframe attachments, and steering stabilizer brackets.
• Automotive & Motorsport Bracing: Strut tower braces, sway bar end links, roll cage attachments, and seat bracket mounting hardware.

Installation & Torque Guidelines

Ensure female threads are clean and free of old debris. Apply a thin layer of anti-seize paste or medium-strength thread locker to the threads. Torque to 38–42 N·m (28–31 lb-ft) using a calibrated manual torque wrench with a quality Torx T50 socket bit (always verify with vehicle manufacturer service manual).
