Grade 5 Titanium Socket Head Cap Bolts for Motorcycles & Automotive - China Suppliers & Factory
Key Features
● High Strength-to-Weight Ratio
Each Titanium Socket Head Cap Bolt is made from aerospace-grade Ti-6Al-4V, offering up to 55% weight reduction compared to steel while maintaining ≥900 MPa tensile strength. 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 low-profile cylindrical head installs flush with the surface, combining aesthetics with functionality and saving space. 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.
