Grade 5 Titanium Dual Drive Race Spec Bolts - Reliable Performance Bolts from China Suppliers & Factory
Key Features
Reliable Dual-Drive Interface
The titanium race spec bolt combines a 12-point outer drive with an internal Torx socket for efficient torque transfer. Even if one interface wears, the other still engages, preventing downtime during repeated maintenance.
Functional Scalloped Race Head Design
Scalloped cuts and recessed top remove non-structural material while keeping clamp performance predictable. This reduces weight and gives your build a race inspired, precision engineered appearance.
Gr5 Titanium Strength-to-Weight Advantage
Made from Ti-6Al-4V, these titanium race spec bolts match the strength of Grade 10.9 steel while weighing only 55%. Lower unsprung mass enhances handling sensitivity, and making assemblies more responsive.
Precision-Engineered Narrow Flange
The compact flange fits tight pockets on calipers, covers, and other precision parts without modifications. It ensures proper seating and reliable clamp contact for consistent assembly.
Weather Stable Premium Finish
Titanium naturally resists corrosion in wet and harsh conditions. Hard PVD gold/black and anodized burnt blue/rainbow finishes hold color and resist scratches. Each batch is carefully checked to keep exposed bolts uniform and visually consistent.
Installation & Maintenance Guidance
● Dual-Drive Flexibility: Use a 12-point socket for high-torque assembly. The internal Torx is perfect for quick access in restricted spaces.
● Torque Recommendation: Set tightening torque to about 85–90% of the equivalent steel bolt value. When a project torque spec is provided, always follow that value.

Application Scenarios
1. Motorcycle Performance & Maintenance
● Brake Calipers & Disc Rotors
The titanium race spec bolt secures caliper brackets and rotor carriers with precise torque. M6–M8 bolts in 20–40 mm lengths allow repeated service without slipping, ensuring reliable braking and smooth maintenance.
● Engine Covers & Precision Panels
Used on clutch covers, generator housings, and compact side cases. Its narrow flanges fit tight counterbores and keep bolts neatly aligned. These titanium race spec bolts provide easy maintenance while preserving a sleek mechanical look.
2. Performance Automotive Engine Bay
Applied on intake manifolds, valve covers, and exposed mounting points. M6–M10 sizes match threaded bosses and sit neatly in tight assemblies. The dual-drive interface supports repeated removal while keeping components aligned and visually consistent.
3. High-End Bicycle & Racing Components
Selected for crank mounts and brake system sub-assemblies requiring accurate tool engagement. The drive design simplifies disassembly during seasonal maintenance or performance tuning, keeping connections secure.
Frequently Asked Questions
What are the advantages of Grade 5 Titanium race spec bolts over steel bolts?
Grade 5 Titanium (Ti-6Al-4V) bolts offer the same strength as Grade 10.9 steel bolts but weigh only 55% as much. This reduction in unsprung mass enhances handling sensitivity and responsiveness while providing exceptional corrosion resistance in harsh environments.
Why is the dual-drive interface design beneficial?
The dual-drive interface combines a 12-point outer drive with an internal Torx socket. This design ensures highly efficient torque transfer. If one drive interface experiences wear or damage over time, the alternative interface can still be engaged to prevent maintenance downtime.
What torque settings should be used when installing these titanium bolts?
It is recommended to set the tightening torque to approximately 85–90% of the equivalent steel bolt value. However, if a specific project torque specification is provided by the manufacturer, you should always prioritize and follow that value.
What sizing options and finishes are available?
We offer diameters ranging from M6 to M10 and lengths from 15 to 60 mm (custom sizes are available upon request). Finish options include Natural, Gold, Black, Burnt Blue, and Rainbow, processed via anodizing or PVD coating.
Can these titanium race spec bolts be customized?
Yes, we support full OEM customization including thread type, head style, finish, and length. Custom logo engraving is also available for custom retail sets or bulk orders.
