SPARTS M8 A3 Titanium Bolts TC4 Standard Head Fasteners

The S-PARTS STAN A3 Series M8 titanium bolts are designed for full motorcycle and electric motorcycle hardware upgrades, and are also suitable for bicycles and a wide range of equipment applications. The product covers multiple compatible mounting positions and is intended to replace OEM fasteners, achieving weight reduction, improved strength, and a unified premium appearance across the entire vehicle or device.

This is a standalone titanium fastener product, not a motorcycle or functional mechanical component. It is intended solely for upgrading standard mounting points across compatible applications.

Material & Manufacturing Process

• Material: S-grade TC4 titanium alloy (Ti-6Al-4V)
• Manufacturing: CNC precision machining
• Bolt head: forged at 650°C high temperature
• Logo process: custom S-PARTS stamping dies
• Quality standard: each die limited to ≤300 uses to ensure long-term precision and consistency

Under the same specifications, this titanium fastener series offers strength comparable to 10.9-grade steel while being close to aluminum in weight, achieving an optimal balance of high strength and lightweight performance for demanding applications.

Key Features

• High-strength structure suitable for both critical and non-critical mounting points
• Significant weight reduction for overall lightweight optimization
• Excellent corrosion and oxidation resistance
• Precision tool interface reduces risk of stripping
• Multiple sizes and color options for a unified aesthetic

Length & Weight Reference (M8 A3 Series)

Length range: 10 mm – 120 mm (refer to detailed chart for each size)
Weight values are approximate per bolt; slight variation ±0.1 g may occur due to anodizing process.

Color Options

Gold, Black, Blue, Titanium, Green, Purple, Candy

Surface Treatment

• Anodizing: enhances color depth and basic corrosion resistance
• Vacuum nitriding: improves surface hardness and long-term wear resistance
• Deep color penetration ensures durability under normal use conditions
• Resistant to rain, mud, and harsh riding environments

Applications

Suitable for motorcycles, electric motorcycles, and bicycles, including but not limited to:

• Frame and exterior component mounting
• Brake and drivetrain components
• Footpegs, brackets, and protective parts
• Bicycle water bottle cages, racks, fenders, and lights
• Motorcycle fairings, mounts, and general fastening points

Application Value

The S-PARTS A3 Series combines lightweight engineering with high-strength titanium material to enhance structural reliability while reducing overall weight. The unified titanium finish improves visual consistency across the entire vehicle or equipment, delivering both performance and aesthetic upgrades.

Important Notice

This is a universal high-end aftermarket titanium fastener product and is not an OEM part supplied by any vehicle or equipment manufacturer. Professional installation is recommended to ensure safety and optimal performance.
