Titanium Bolt M6x10 15 20 25 30 35 40 45mm ISO7380 Button Hex Socket Head Screw for Bicycles and Motorcycles, Pitch 1mm, by Tianswer

Lightweight, low-profile Grade 5 Ti-6Al-4V titanium M6 ISO 7380 button hex socket head screws engineered for sleek aerodynamics, snag-free bicycle cockpits, and motorcycle fairing assemblies.

ISO 7380 Low-Profile Domed Architecture

The standardized ISO 7380 button head profile features a smooth, rounded dome with a 10.5mm outer diameter and a low 3.5mm head height. This curved contour minimizes aerodynamic drag and prevents catching on cycling shorts, riding boots, luggage, and external wiring harnesses. Precision-machined from aerospace Ti-6Al-4V (Grade 5) titanium alloy, it provides a clean, refined factory-racing appearance while cutting weight by more than 45% compared to steel fasteners (weighing just 1.8g to 5.2g per piece).

Engineering Application & Clamping Dynamics

Due to the reduced head height and compact 4mm internal hex drive, ISO 7380 button head screws are specifically engineered for light-to-medium clamping applications, cosmetic panels, and non-structural bracket assemblies rather than high-torque critical tension joints (such as engine cylinder heads or structural suspension pivots). When installed in eligible applications, they deliver exceptional shear strength, fatigue life, and absolute immunity to rust, road salt, and weather exposure.

Key Applications

• Performance Bicycles (Road, Gravel, XC, MTB): Water bottle cage bosses, stem faceplate clamps (where low clearance is desired), headset top caps, seatpost clamp pinch accents, derailleur cable anchors, and rack eyelets.
• Motorcycles & Scooters: Windshield fairing screws, body panel fasteners, license plate mounts, instrument cluster brackets, and radiator guard trims.
• Specialized Assemblies: Drone frames, lightweight camera gimbals, RC car chassis, and custom sim racing cockpit hardware.

Installation & Torque Guidelines

Always use a high-quality, unworn 4mm hex wrench or hex bit fully inserted to the bottom of the drive socket. Apply a small dab of anti-seize paste or medium-strength thread locker to the threads. Torque conservatively to 5–7 N·m (do not exceed 8 N·m) to preserve the shallow internal drive socket and prevent rounding.
