Product Overview

Designed for high-performance racing and premium aftermarket tuning, our Grade 5 Titanium Wheel Bolts offer the perfect balance of lightweight engineering and uncompromised safety. Manufactured from certified Ti-6Al-4V (TC4) aerospace titanium bars, these bolts are engineered to withstand the extreme stresses of track use while significantly reducing rotational mass.

Unlike standard steel bolts, our titanium lug bolts reduce weight by 40-45%, directly lowering the vehicle’s unsprung weight. This translates to faster suspension response, improved handling precision, and quicker acceleration/braking dynamics. Whether for a dedicated track car or a high-end stance build, these bolts provide the mechanical reliability required by professional race teams

Engineered for Safety and Precision

We utilize a Hot Forging process for the bolt heads and Thread Rolling technology for the threads. This combination ensures continuous grain flow and superior fatigue resistance, addressing the common failure points found in cheaper, CNC-machined titanium bolts.

Why Choose Our Titanium Wheel Bolts?

  • True Grade 5 Certification: Sourced strictly from ASTM B348 compliant Ti-6Al-4V bars. We provide MTC (Material Test Certificate) for every batch to verify chemical composition (Al 5.5-6.75%, V 3.5-4.5%).
  • Superior Fatigue Life: Hot forged heads eliminate internal voids and stress risers, offering 30% higher fatigue strength than machined heads.
  • Anti-Seize Performance: Rolled threads (Class 6g) provide a smoother surface finish, reducing the risk of galling and ensuring accurate torque application.
  • Specialty Fitment: Available in Flat Head (with floating washer options) for specific aftermarket wheels, as well as standard Cone (60°) and Ball seats.
  • OEM Ready: We support low MOQ (100pcs) for custom PVD colors and laser logo engraving, ideal for private label brands.

Why “Forged + Rolled” Matters for Safety?

In the world of wheel fasteners, manufacturing method dictates safety. We strictly avoid “all-machined” production for load-bearing bolts.

1. Hot Forged Heads (vs. CNC Machined)

Our bolt heads are formed by hot forging. This process aligns the grain structure of the titanium alloy with the shape of the head.

  • Benefit: Prevents head separation under high impact or tensile loads.
  • Contrast: CNC machining cuts across the grain flow, creating potential weak points where cracks can propagate.

2. Rolled Threads (vs. Cut Threads)

Threads are formed by cold rolling dies under high pressure, rather than cutting material away.

  • Benefit: This process work-hardens the thread surface, increasing shear strength and fatigue life by up to 30%. The mirror-like finish of rolled threads also significantly reduces friction and the risk of galling (cold welding), a common issue with titanium.

Customization & Surface Finishes

Empower your brand with our diverse customization options. We use PVD (Physical Vapor Deposition) technology for black and gold finishes, which offers superior wear resistance compared to standard anodizing.

  • Polished: A mirror-like, classic titanium look.
  • Burnt Blue: The iconic gradient blue-purple finish, achieved through precise anodizing.
  • Black PVD: A diamond-like carbon coating for stealth looks and maximum scratch resistance.
  • Gold PVD: A luxurious, durable gold finish.
  • Custom Logo: We offer Laser Etching on the bolt head.
    • MOQ: 100 pcs per design.
    • Application: Ideal for tuning shops and wheel brands looking to build brand identity.

Installation & Safety Guidelines

Titanium bolts require correct installation practices to ensure safety and performance.

Recommended Torque Specifications

Always verify with the vehicle manufacturer’s manual. Do NOT overtighten.

Bolt Size Recommended Torque Range (Dry) Notes
M12 x 1.25 / 1.5 110 – 130 Nm (80 – 95 ft-lbs) Common for JDM & smaller vehicles
M14 x 1.25 / 1.5 125 – 145 Nm (90 – 105 ft-lbs) Common for European & Performance cars

Critical Installation Tips

  1. Hand Tools Only: NEVER use an impact gun (air or electric) to install titanium bolts. Impact tools can damage the finish and over-torque the threads.
  2. Anti-Seize Compound: We recommend applying a small amount of copper or nickel-based anti-seize to the threads to prevent galling. Note: If using anti-seize, reduce torque settings by ~10-15% as it acts as a lubricant.
  3. Check Seat Type: Ensure the bolt seat (Cone/Ball/Flat) matches your wheel perfectly. Using the wrong seat type (e.g., Cone bolt on Ball seat wheel) can lead to loosening and wheel failure.

Quality Assurance

Quality is our baseline. Every batch of titanium wheel bolts undergoes rigorous testing before shipment.

  • Material Verification: Spectroscopic analysis to confirm Ti-6Al-4V composition.
  • Mechanical Testing: Tensile and proof load testing per ASTM E8.
  • Dimensional Check: 100% thread inspection using Go/No-Go gauges (6g tolerance).
  • MTC Provided: A Material Test Certificate is available with every bulk order for your technical filing.

Frequently Asked Questions (FAQ)

Q: Are Grade 5 titanium bolts strong enough for racing?

A: Yes. Grade 5 (Ti-6Al-4V) has a tensile strength of over 895 MPa, which is comparable to Grade 10.9 steel bolts commonly used in automotive applications. Our forged production process further ensures they meet the fatigue requirements of racing environments.

Q: Will titanium bolts rust in winter conditions?

A: No. Titanium is virtually immune to corrosion from road salts, snow, and water. Unlike steel bolts that rust and seize over time, titanium remains corrosion-free for the life of the vehicle.

Q: What is the lead time for custom PVD colors (e.g., Black/Gold)?

A: For orders under 500 pieces, the lead time is typically 7-12 days. PVD coating requires batch processing to ensure color consistency.

Q: Do you offer “Flat Head” bolts with washers?

A: Yes. As shown in our specifications, we manufacture Flat Head bolts, often used with floating washers for specific aftermarket wheels (like Peugeot/Citroen fitments or specialized forged wheels). The floating washer design helps protect the wheel’s paint finish during tightening.

Q: Can I get a sample kit before a bulk order?

A: Absolutely. We offer a sample kit containing M12/M14 bolts in different colors/seats for you to verify the weight, thread quality, and finish. Contact us to request yours.
