Premium Grade 5 Titanium (Ti-6Al-4V)

Every S-PARTS titanium fastener is manufactured from carefully selected aerospace-grade Grade 5 Titanium.

Compared with conventional steel fasteners, it offers:

• Approximately 45–50% lighter weight
• Average tensile strength exceeding 1050 MPa
• Outstanding strength-to-weight ratio
• Excellent corrosion resistance
• Will not rust like ordinary steel hardware

Its overall mechanical performance is comparable to high-strength Class 10.9 steel fasteners while delivering significant weight savings.

Precision CNC Manufacturing

Each bolt is manufactured using high-precision CNC machining with micron-level tolerance control for:

• Accurate threads
• Smooth engagement
• Excellent concentricity
• Reliable long-term performance

To ensure exceptional dimensional consistency, every bolt head is hot forged using exclusive S-PARTS tooling before precision machining.

Premium Surface Finishes

PVD Vacuum Nitriding

Available in:

• Gold
• Oil Slick
• Black
• Blue

These finishes receive an advanced PVD vacuum nitriding treatment that creates a dense metallic nitride layer, improving:

• Surface hardness
• Wear resistance
• Scratch resistance
• Impact resistance
• Long-lasting colour durability

The finish is integrated into the surface rather than simply coated, helping it withstand years of riding.

Titanium Anodized Finish

Available in:

• Green
• Purple
• Candy
• Indigo

These colours are produced through a precision anodizing process.

Instead of using paint or pigments, controlled oxide layers create vibrant colours through the natural interference of light.

The result is:

• Excellent corrosion resistance
• Increased surface hardness
• Lightweight finish
• Brilliant metallic colours unique to titanium
