Grade 5 Titanium Dual Drive Race Spec Bolt - Premium China Suppliers & Factory for Motorcycle Performance Builds
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.

● 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
● Intake Manifolds & Valve Covers
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
● Crank Mounts & Brake Assemblies
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 key benefits of the dual-drive interface design?
The dual-drive system integrates a 12-point external drive with an internal Torx drive. This provides two tool options for tightening and removal, ensuring reliable torque transfer and preventing installation failure even if one drive interface becomes worn.
Q
How much weight can I save by using Grade 5 Titanium race spec bolts?
Grade 5 Titanium (Ti-6Al-4V) bolts offer the same tensile strength as Grade 10.9 steel while weighing only 55% of steel's weight. This helps reduce unsprung mass and improves overall handling responsiveness in racing applications.
Q
What torque settings should be applied to these titanium bolts?
It is generally recommended to set the tightening torque to approximately 85–90% of the value specified for equivalent steel bolts. If the specific project or assembly guide lists a dedicated torque specification, you should prioritize and follow that value.
Q
Are these titanium bolts suitable for wet or corrosive environments?
Yes. Grade 5 Titanium naturally forms a stable oxide layer that provides excellent resistance to corrosion in wet, marine, and chemically harsh environments. The PVD and anodized finishes further enhance surface durability and scratch resistance.
Q
Can I order custom sizes or finishes for OEM applications?
Yes, we support comprehensive OEM customization. You can customize the thread type, head style, length, and finish options (including Natural, Gold, Black, Burnt Blue, and Rainbow), along with custom logo engraving and packaging solutions.
