Grade 5 Titanium Dual Drive Race Spec Bolts - China Suppliers & Factory for Motorcycle Performance Applications
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 the dual-drive interface on these bolts?
The dual-drive interface combines a 12-point outer drive with an internal Torx socket. This design ensures efficient torque transfer and provides a backup engagement method; if one drive interface wears down, the other can still be used, preventing downtime.
How much lighter are Grade 5 Titanium bolts compared to standard steel bolts?
Grade 5 Titanium (Ti-6Al-4V) bolts weigh only 55% of the weight of Grade 10.9 steel bolts while matching their overall strength. This reduction in unsprung mass helps improve handling sensitivity and assembly responsiveness.
What is the recommended installation torque for these titanium bolts?
It is recommended to set the tightening torque to approximately 85–90% of the value specified for an equivalent steel bolt. However, if a specific project torque spec is provided, you should always follow that exact value.
Are these titanium race spec bolts resistant to harsh weather and corrosion?
Yes. Titanium naturally exhibits excellent corrosion resistance under wet and harsh conditions. Additionally, the premium finishes (such as hard PVD gold/black and anodized burnt blue/rainbow) are scratch-resistant and retain their color well.
Can I order custom sizes or custom finishes for these bolts?
Yes, OEM customization is fully supported. You can request custom thread types, head styles, lengths, and finishes (including Natural, Gold, Black, Burnt Blue, and Rainbow). Logo engraving is also available.
What is the function of the scalloped race head design?
The scalloped cuts and recessed top remove non-structural material to reduce weight without compromising predictable clamp performance. It also gives the assembly a clean, precision-engineered, race-inspired appearance.
