Titanium Flanged Concave Hex Head Bolts | China Suppliers & Factory for Motorcycle & Performance Use
Key Features
The titanium flanged concave hex head bolts feature a sculpted concave head profile that removes excess material while preserving strength. This carefully balanced geometry helps reduce the unsprung weight in motorcycles and sports vehicles, improving suspension response and cornering stability.
The integrated head and flange design of each titanium flanged concave hex head bolt ensures even torque transfer across the contact area, minimizing stress concentration and maintaining fastening stability under vibration or repeated dynamic loads.
The curved head fits smoothly against fairings, calipers, and body panels, providing both aerodynamic efficiency and a refined appearance. Ideal for custom motorcycles and high-performance modifications.
Every bolt surface and thread is CNC-machined with rolled threading for superior fatigue resistance, tight tolerance, and uniform preload retention. These qualities make the bolt reliable across multiple installation cycles.
Available in anodized rainbow, blue, black, or gold finishes, the titanium flanged concave hex head bolt offers lasting corrosion protection with a premium appearance. Optional PVD coating and laser engraving support OEM branding or personalized customization.
Installation & Maintenance Guidance
- Apply a high-quality anti-seize compound when connecting titanium to titanium or titanium to aluminum to prevent galling.
- Torque bolts to specification using a calibrated wrench; over-torquing can deform the concave head.
- Inspect fasteners periodically after high-stress or track use to maintain clamping reliability.
