Titanium Motorcycle Bolts M5 Torx Flange Head

Titanium Motorcycle Bolts M5 M6 M8 Torx Flange Head is a high-strength, corrosion-resistant fastener widely used in demanding fields such as aerospace, automotive modification, medical equipment, and chemical processing. It combines the lightweight corrosion resistance of titanium alloy with the anti-loosening properties and internal hex drive structure of flange heads, offering excellent fatigue resistance and installation convenience.

It is typically manufactured from Ti-6Al-4V or Gr2 industrial pure titanium, with a density of approximately 4.5 g/cm³. Offering high strength and lightweight properties, it reduces weight by over 40% compared to steel bolts of the same specifications. Featuring exceptional resistance to high temperatures (operating up to 300°C), seawater corrosion, and non-magnetic characteristics, it is suitable for extreme environments.

• Flange Head: Features an integrated flange beneath the bolt head, replacing flat washers to increase contact area, distribute pressure, prevent loosening, and avoid surface damage. The head features a flange that evenly distributes compressive stress, preventing loosening and minimizing damage to mating surfaces. It is commonly used in mechanical systems subject to frequent vibration.
• Torx Head: Features a 6-point star-shaped recessed drive slot. Compared to hex sockets, it offers greater contact area, higher torque transfer efficiency, reduced slippage, and enhanced tamper resistance.(Torx Plus or Hexagon Socket): Compared to traditional hexagonal internal holes, it offers higher torque transmission capacity, reduces the risk of stripping, and enhances assembly efficiency and safety.
• Titanium Alloy: Primarily Ti-6Al-4V, GR5, also utilizing pure titanium grades Gr1/Gr2, BT20(Ti-6.5AL-1Mo-1V-2Zr), Ti-8823, etc. Balances high strength, low density, superior corrosion resistance, non-magnetic properties, and biocompatibility.

1. Lightweight: 43% lighter than steel of the same specification. M6×12 weighs only 1.8 g (steel: 3.2 g), achieving significant weight reduction.
2. High Torque / Anti-Stripping: 50% larger contact area than hex sockets, 30% higher anti-stripping torque, 15° drive angle for high torque efficiency.
3. Reliable Anti-Loosening: Precise fit between flange face and hexagon head maintains >90% preload retention in vibration environments, preventing loosening.
4. Superior Corrosion Resistance: Outperforms 316 stainless steel, suitable for seawater, chemical, coastal, and high-humidity environments.
5. Non-magnetic / Non-toxic: Does not interfere with magnetic fields; biocompatible for medical, electronic, and precision instrument applications.
6. High/Low Temperature Resistance: Stable across wide temperature ranges, suitable for aerospace, aviation, and polar equipment.

• Aerospace: Aircraft structures, engines, satellite mounts, drones-weight reduction + corrosion resistance + high strength.
• Automotive / Racing / Motorcycles: Engines, chassis, brakes, wheels, aftermarket parts-weight reduction for enhanced performance.
• Medical: Orthopedic implants, surgical instruments, biocompatible, non-magnetic, resistant to bodily fluid corrosion.
• Chemical / Marine: Piping, valves, seawater equipment, acid/alkali resistant, seawater resistant.
• Electronics / Precision: Instruments, communication devices, non-magnetic, lightweight, tamper-proof.
• Sports Equipment: Bicycles, skiing gear, lightweight + high strength + aesthetic appeal.
