Titanium Bolt M6x10 15 18 20 25 30 35 40 45 50 55 60 65 70mm DIN912 Column Hex Socket Head Screw for Bike Motorcycle, Pitch 1mm, by Tianswer

Universal structural-grade Aerospace Ti-6Al-4V Grade 5 titanium M6 DIN 912 (ISO 4762) cylindrical socket head cap screws engineered for motorcycle engine case covers, disc brake caliper mounts, bicycle suspension linkages, and motorsport chassis hardware.

DIN 912 / ISO 4762 Heavy-Duty Cylindrical Head Profile

The DIN 912 cylindrical socket head cap architecture is the industry standard for high-tension mechanical joints. Featuring a solid 10.0mm diameter head with a full 6.0mm head height, it accommodates a deep, precision-broached 5mm internal hex drive socket. Unlike shallow button or countersunk fasteners, the deep hex pocket provides comprehensive tool engagement, allowing mechanics to apply full tightening torques without fear of tool cam-out or stripping the socket corners.

Dual Thread Profile: Full Thread vs. Partial Shank Shear Resistance

Engineered to match specific mechanical shear and clamping requirements across varying bolt lengths:

• Lengths ≤ 25mm: Fully threaded from tip to head, maximizing thread engagement in shallow blind holes such as motorcycle engine clutch covers, water pump housings, and crankcase side covers.
• Lengths > 25mm: Features a standardized ~23mm rolled thread section paired with a precision-ground unthreaded cylindrical shank. In high-shear applications—such as bicycle suspension pivot pivots, brake caliper post mounts, or footpeg brackets—the solid unthreaded shank bridges the joint shear interface, providing maximum cross-sectional area and exceptional resistance to cyclic shear fatigue.

Aerospace Grade 5 (Ti-6Al-4V) Strength & 45% Weight Reduction

Precision CNC-machined from certified Grade 5 Ti-6Al-4V titanium alloy, these fasteners achieve a minimum tensile strength of 950–1050 MPa (matching Class 10.9 high-tensile alloy steel). Weighing roughly 45% less than steel bolts, upgrading multiple chassis and engine fasteners reduces overall vehicle mass and lowers the center of gravity, while titanium's self-healing oxide ceramic barrier ensures total immunity to road salt, mud, high-pressure washes, and harsh weather.

Key Applications

• Motorcycles & Powersports: Engine clutch and stator side covers, water pump housings, exhaust hanger brackets, handlebar clamp pinch bolts, front fender mounts, and chain guard stays.
• Mountain Bikes & Road Bicycles: Disc brake caliper post-mount adapters, rear suspension frame pivot linkages, heavy-duty handlebar stem clamps, and crankarm pinch bolts (Shimano Hollowtech II compatible).
• Motorsport & Go-Karts: Radiator stay brackets, undertray hardware, steering column brackets, and bodywork panel anchors.

Installation & Torque Guidelines

Clean internal threads thoroughly before assembly. Always apply a thin film of anti-seize paste or synthetic grease to the thread flanks to prevent galling under high clamp preloads. Torque using a calibrated manual torque wrench with a quality 5mm hex bit to 9.0–11.0 N·m (80–97 in-lb) for standard mechanical fixtures, or follow specific vehicle service manual torque ratings.
