Grade 5 Titanium Socket Head Cap Bolts for Motorcycle and Automotive Applications
Key Features
● High Strength-to-Weight Ratio
Each Titanium Socket Head Cap Bolt is made from Grade 5 Ti-6Al-4V titanium. It is approximately 40–45% lighter than an equivalent steel bolt and has a tensile strength of ≥900 MPa. It is suitable for performance assembly applications that require extremely high strength and efficiency.
● Deep Hex Socket for Maximum Torque
The deep hex socket design allows higher tightening torque without stripping, especially in confined spaces or precision assemblies. It guarantees consistent torque tightening, which is particularly critical for high-performance engines and precision instruments.
● Compact Cylindrical Head Design
The cylindrical socket head provides a compact profile for space-limited applications. This feature is particularly valued in motorcycle and automotive assembly for enhancing both aesthetics and aerodynamic performance.
● CNC Precision Machining & Cold Rolled Threads
Each bolt is CNC-machined with ±0.05 mm tolerance for perfect concentricity. Cold-rolled threads deliver fatigue resistance and smooth engagement, withstanding frequent assembly and disassembly cycles without wear or galling.
● Surface Finish & Customization Options
Available in polished, anodized, or PVD-coated finishes for both visual appeal and durability. Custom colors, logo engraving, and OEM packaging also be provided to meet specific branding or technical requirements.
● Corrosion & Heat Resistance in Fastening
Titanium Socket Head Cap Bolts are engineered to perform reliably in salt, moisture, and thermal cycling conditions. They operate effectively between −100 °C and +450 °C, maintaining clamping stability even in high-temperature zones such as exhaust manifolds or brake assemblies.
Installation & Maintenance Guidance
For titanium-to-titanium or titanium-to-aluminum connections, we recommend using high-quality anti-seize compound to prevent galling, ensure accurate torque and extends thread life.

Application Scenarios
Titanium socket head cap bolts are trusted in industries that demand strength, precision, and corrosion resistance with minimal weight.
🏍 Motorcycle Upgrades
Commonly used in frame joints (M6–M10), brake calipers (M8–M10), and engine covers (M5–M8). The combination of weight reduction and high torque capacity enhances vehicle handling, stability, and long-term durability for performance and racing applications.
🚗 Automotive Performance
Ideal for intake manifolds (M6–M8), suspension brackets (M8–M12). and lightweight chassis components (M10–M12). Titanium socket head cap bolts reduce unsprung mass while maintaining fastening security in high-vibration and high-temperature zones.
🚲 Bicycle & E-bike Components
Applied in stem clamps (M5–M6), disc rotors (M5), and crank interfaces (M6–M8), enhancing stiffness and long-lasting corrosion resistance. Perfect for riders pursuing lightweight performance without compromising reliability.
🏭 Industrial & Aerospace Equipment
Engineered for robotic arms, instrument housings, pressure vessels, and lightweight structural frames (M8–M16). The high fatigue strength of Grade 5 Titanium ensures consistent performance under vibration and thermal stress.
Frequently Asked Questions
Q1. Are Grade 5 titanium socket head cap bolts stronger than stainless steel bolts?
A: Yes. Grade 5 titanium (Ti-6Al-4V) offers a higher strength-to-weight ratio than most stainless steel fasteners while weighing significantly less. It is widely used in motorcycles, automotive performance applications and industrial equipment that require high strength and reduced weight.
Q2. Can Grade 5 titanium socket head cap bolts be reused?
A: Yes, provided the bolts show no signs of thread damage, deformation or excessive wear. Always inspect the fasteners before reuse and follow the recommended tightening procedure. For critical safety applications, always follow the manufacturer replacement recommendations.
Q3. Should anti-seize compound be used when installing titanium bolts?
A: Yes. A suitable anti-seize compound helps reduce thread galling during installation. It is recommended when titanium bolts are used with titanium or stainless steel threaded parts.
Q4. Can these titanium socket head cap bolts be customized?
A: Yes. Custom diameters, lengths, thread pitches, head dimensions and surface finishes are available for OEM projects and specialized applications. We can manufacture according to your drawings or technical requirements.
