Grade 5 Titanium Dual Drive Race Spec Bolt - China Suppliers & Factory for Motorcycle and Performance Vehicles
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
● Installation & Mounts
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
Q: What are the benefits of the dual-drive interface on these titanium bolts?
The dual-drive interface features a 12-point outer drive paired with an internal Torx socket. This design ensures efficient torque transfer and provides a backup option; if one drive interface wears or gets damaged, the other can still be engaged to prevent downtime during maintenance.
Q: How much weight can I save by using Grade 5 Titanium bolts instead of steel?
Grade 5 Titanium (Ti-6Al-4V) bolts match the strength of Grade 10.9 steel but weigh only 55% as much. This reduction in unsprung mass improves handling sensitivity and responsiveness in racing and high-performance applications.
Q: What is the purpose of the scalloped race head design?
The scalloped cuts and recessed top are engineered to remove non-structural material to minimize weight while ensuring that the clamp performance remains predictable and secure. Additionally, it gives the assembly a high-end, race-inspired appearance.
Q: What torque settings should be applied during installation?
It is recommended to set the tightening torque to approximately 85–90% of the value specified for equivalent steel bolts. However, if a specific project torque specification is provided by the manufacturer, you should always prioritize and follow that value.
Q: Are these titanium race spec bolts resistant to corrosion and weather?
Yes. Titanium naturally exhibits excellent corrosion resistance in wet and harsh environments. Furthermore, our premium PVD finishes (gold, black) and anodized finishes (burnt blue, rainbow) offer enhanced scratch resistance and long-lasting color stability.
Q: Can these bolts be customized for specific OEM requirements?
Yes, we support OEM customization. Options include custom thread types, head styles, finishes, specific lengths, and custom logo engraving to meet your specific application needs.
