Descriptions
Titanium Wheel Bolts are precision-engineered fasteners made from high-strength
titanium alloys. They are commonly used in both automobiles and bicycles for their exceptional combination of lightweight, high strength, and excellent corrosion resistance.
Titanium wheel bolts are available through various automotive and
cycling parts retailers, typically sold in sets. The required size
depends on the specific application — common thread sizes include M5, M6, and M8.
Compared with conventional steel bolts, Titanium Grade 5 (Ti-6Al-4V) Wheel Screws provide significant advantages in weight reduction and durability, making them ideal for high-performance and outdoor environments.
Although titanium bolts are more expensive, their long service life and superior performance make them a valuable investment for enthusiasts and professionals
alike.

Applications of Titanium Wheel Bolt for Automobile and Bicycle
Automobile: Used for high-performance car wheels, suspension systems, and
engine assemblies
Bicycle: Ideal for lightweight frames, hubs, cranksets, and brake rotors
Motorcycle: Commonly used for wheel assemblies and racing components
Marine and Outdoor Equipment: Perfect for corrosion-prone environments
Advantages of Titanium Wheel Bolt for Automobile and Bicycle
High Specific Strength
Titanium offers a density of 4.51 g/cm³ — lighter than steel but
with far greater strength, ideal for reducing overall vehicle or
bicycle weight.
Excellent Corrosion Resistance
Titanium is resistant to corrosion in most environments, making
these bolts suitable for coastal, marine, and outdoor use.
Outstanding Temperature Performance
Operates reliably from –250°C to 600°C without deformation or loss of strength.
Non-Magnetic and Biocompatible
Titanium bolts are non-magnetic, non-toxic, and biocompatible, making them safe for both industrial and medical uses.
Strong Vibration Damping
Titanium exhibits superior vibration damping characteristics
compared to steel or copper, enhancing ride comfort and performance
stability.
