Why Choose S-PARTS Grade 5 Titanium?

Aerospace-Grade Material

Every fastener is manufactured from carefully selected Grade 5 Titanium (Ti-6Al-4V).

Through rigorous material selection and continuous batch verification, our titanium achieves an average tensile strength exceeding 1050 MPa, significantly exceeding the 895 MPa minimum requirement for standard Grade 5 titanium.

Compared with conventional steel hardware, S-PARTS titanium fasteners provide:

• Approximately 45–50% lower weight
• Comparable overall mechanical performance to Grade 10.9 steel fasteners
• Outstanding corrosion resistance
• Excellent fatigue resistance
• Rust-free performance in all weather conditions

Precision Manufacturing

Every bolt head is hot forged using exclusive S-PARTS tooling before precision CNC machining.

To maintain exceptional dimensional accuracy, each forging die is retired after fewer than 300 production cycles, ensuring consistent quality throughout every production batch.

Military-grade multi-axis CNC machining with micron-level tolerance control provides:

• Precise thread engagement
• Excellent tool fit
• Smooth installation
• Reliable torque consistency
• Premium surface finish

Premium Surface Finishes

PVD Vacuum Nitriding

Available in:

• Gold
• Rainbow (Oil Slick)
• Black
• Blue

PVD Vacuum Nitriding creates an extremely hard titanium nitride surface layer that offers:

• Increased surface hardness
• Improved wear resistance
• Enhanced scratch resistance
• Superior corrosion protection
• Deep metallic colors with excellent fade resistance

Unlike painted coatings, the finish becomes part of the titanium surface itself.

Titanium Anodized Finish

Available in:

• Green
• Purple
• Candy
• Indigo

These colors are produced through an electrochemical anodizing process rather than paint or pigments.

The oxide layer creates brilliant metallic colors through light interference while maintaining excellent corrosion resistance.

Installation Notes

For proper hydraulic sealing, please reuse the original SRAM sealing O-rings when reinstalling the following components:

• ① Shifter Bleed Port Screws
• ⑥ Caliper Body Bolts
• ⑧ Caliper Bleed Port Screws

Failure to reinstall the factory sealing rings may affect brake system sealing performance.

Always tighten all fasteners according to SRAM's official torque specifications.
