Our Rison Titanium Caliper Bolts have more than 10 colors with about 50 different sizes.
Titanium (Grade 5, Ti-6Al-4V) caliper bolts are widely used in high-performance automotive, motorsports,
and cycling due to their lightweight, corrosion resistance, and strength. Below are the standard sizes,
torque specs, and applications.
1. Common Sizes & Specifications
| Bolt Type | Thread Size (Metric) | Length (mm) | Head Type | Typical Torque (Nm) | Material |
|---|---|---|---|---|---|
| Disc Brake Caliper | M6 x 1.0 | 20-30 | Hex Socket (Allen) | 10-15 | Ti-6Al-4V (Grade 5) |
| Floating Mount | M8 x 1.25 | 25-40 | Hex Head or Socket | 25-35 | Ti-6Al-4V |
| Bracket Bolt | M10 x 1.25 | 30-50 | Hex Head | 40-50 | Ti-6Al-4V |
| Pinch Bolt | M6 x 1.0 | 15-25 | Button Head | 8-12 | Ti-6Al-4V |
| Bleeder Valve | M7 x 1.0 (Special) | 15-20 | Hex Socket | 6-10 | Ti-6Al-4V |
Notes:
- Thread Pitch: Fine threads (e.g., M6x1.0) are more common for precision applications.
- Length: Depends on caliper thickness + mounting adapter (always check clearance).
- Torque: Titanium requires 10-15% lower torque than steel to avoid galling.
2. Primary Applications
① Automotive (Track/Race Cars)
- Use Case: Replacing steel caliper bolts to reduce unsprung weight.
- Benefits:
- Weight Savings: ~40% lighter than steel (e.g., M8x30 bolt: 10g Ti vs. 17g steel).
- Corrosion Resistance: No rust in wet/salty conditions.
- Example Vehicles:
- Porsche 911 GT3 (aftermarket upgrades)
- Formula 1/NASCAR (custom PVD-coated Ti bolts)
② Motorcycles (Sport/Adventure Bikes)
- Use Case: Lighter braking system = improved handling.
- Critical Specs:
- M6-M8 bolts for radial-mount calipers (e.g., Brembo, Nissin).
- Anodized (blue/gold) for corrosion protection + aesthetics.
- Example Bikes:
- Ducati Panigale V4
- KTM 1290 Super Adventure R
③ High-End Bicycles (Road/MTB)
- Use Case: Reducing rotating mass for better acceleration.
- Common Sizes:
- M6x20mm (Shimano/SRAM disc brake mounts).
- M5x12mm (cantilever/V-brake pivots).
- Weight Impact: Saving 5-10g per bolt adds up in competitive cycling.
④ Aerospace & Marine
- Use Case: Saltwater/chemical resistance in extreme environments.
- Special Features:
- Self-locking (nylon patch or distorted thread).
- PVD-coated for extra wear resistance.
3. Installation & Maintenance Tips
✔ Do’s
- Use Anti-Seize: Molybdenum disulfide paste prevents galling.
- Torque Properly: Always use a calibrated torque wrench.
- Check Regularly: Inspect for thread wear after track days/off-road use.
✖ Don’ts
- Over-Tighten: Titanium is softer than steel—excess torque strips threads.
- Mix Metals: Avoid direct contact with aluminum (use stainless steel washers).
- Reuse Old Bolts: Discard if threads are damaged.
4. Titanium vs. Steel Caliper Bolts
| Factor | Titanium (Grade 5) | Steel (10.9 Grade) |
|---|---|---|
| Weight | 40-45% lighter | Heavier |
| Corrosion | Immune to rust | Requires coating |
| Strength | 900-1000 MPa tensile | 1040 MPa tensile |
| Cost | $$$ (5-8x more expensive) | $ |
| Best For | Racing, marine, weight-critical uses | Budget builds, daily drivers |
