TSM TECHNOLOGY manufactures high‑strength titanium steering wheel bolts and titanium wheel lug bolts for performance vehicles. Whether you drive a BMW, Porsche, Ferrari, or McLaren, our titanium bolts reduce unsprung weight, resist corrosion, and add a motorsport aesthetic. Custom kits for 3‑piece wheels and track‑focused builds.
Titanium Wheel Bolt Set — M14x1.5 / M12x1.5
Actual: lightweight titanium bolts with ball seat / conical seat options.
Titanium steering wheel bolts are used to secure the steering wheel hub to the steering column, while titanium wheel bolts (or lug bolts) fasten the wheel to the hub. Both applications benefit from titanium's exceptional strength‑to‑weight ratio. At TSM, we forge bolts from aerospace‑grade Ti‑6Al‑4V (Grade 5) and commercially pure Grade 2 for specific needs. Compared to OEM steel bolts, titanium wheel lug bolts are approximately 40% lighter, yet they meet or exceed OEM tensile strength requirements (typically 130,000 psi minimum).
Reducing rotating mass improves acceleration, braking, and suspension response. A set of 20 titanium bolts can save up to 1.2 lbs (0.54 kg) over steel.
Titanium naturally forms a protective oxide layer. No more rusty wheel bolts — ideal for winter driving or coastal areas.
Available in natural titanium silver, gold anodized, or PVD black. A subtle upgrade that enhances any wheel setup.
| Property | Titanium (Grade 5 / Ti-6Al-4V) | OEM Steel (10.9 / 12.9) |
|---|---|---|
| Density (g/cm³) | 4.43 | 7.85 |
| Tensile Strength (MPa) | min 895 (up to 1100) | 1040–1220 (Class 12.9) |
| Yield Strength (MPa) | 828–910 | 940–1100 |
| Corrosion Resistance | Excellent (immune to salt) | Poor without coating |
| Magnetic | Non‑magnetic | Ferromagnetic |
| Thermal Conductivity | Low (less heat transfer to hubs) | Higher |
Our bolts are cold‑headed and thread‑rolled for fatigue resistance, then precision ground.
TSM TECHNOLOGY offers direct‑fit titanium wheel bolts for popular performance cars. Below are our most requested kits. All kits include correct seat type (ball/R13, conical 60°) and thread pitch.
For BMW M models and standard series, we supply bmw titanium wheel bolts in M14x1.25 (most modern) and M12x1.5 (older). Choose from 27mm, 35mm, or 43mm thread lengths. Includes 17mm hex or spline drive. Compatible with OEM BMW wheel locks and spacers. Browse BMW titanium bolt kits →
Porsche titanium wheel bolts (M14x1.5) are engineered for 911, Cayman, Boxster, Panamera, and Macan. We offer both ball seat (R13) and conical seat variants. Titanium wheel bolts porsche owners trust for track days and concours events. Lightweight titanium reduces rotational inertia. Porsche titanium bolt sets →
Ferrari titanium wheel bolts demand absolute precision. Our bolts match OEM specifications for 458, 488, F8, and Roma. Typically M14x1.5 with special under‑head profile. PVD black or natural finish. Maintain that Prancing Horse pedigree with titanium. Ferrari titanium bolts →
Mclaren titanium wheel bolts for MP4-12C, 650S, 720S, and Artura. McLaren uses unique bolt lengths and torque values. We replicate the exact geometry in Grade 5 titanium, saving weight on every corner. McLaren titanium bolts →
For motorsport and forged 3‑piece wheels, we manufacture titanium 3 piece wheel bolts — the fasteners that join the wheel center to the barrel halves. These bolts are subjected to high shear loads and must be ultra‑reliable. Our titanium 3‑piece bolts are available in M7, M8, and M10 sizes with 12‑point or Torx® drive. Custom lengths and under‑head profiles ensure perfect clamping without stress risers.
Also available: Titanium wheel assembly hardware kits including nuts and washers.
| 3‑Piece Wheel Bolt Kit | Weight comparison: Steel vs Titanium | Anodized finishes |
| Grade 5 titanium, M8 x 30mm, 12‑point head. | Steel bolt ~58g, titanium bolt ~33g (M14x1.5). | Gold, blue, black, and natural titanium. |
6. Are Titanium Wheel Bolts Worth It? Value Analysis
Titanium wheel bolts cut unsprung weight by roughly 40% compared to steel, sharpening steering response and ride quality. They never rust, even after harsh winters, and add a clean, premium finish. For track enthusiasts or anyone tired of corroded fasteners, the long‑term durability and aesthetics make the upgrade genuinely worth it.
| Vehicle / Application | Thread Size | Seat Type | Torque (dry) | Socket |
|---|---|---|---|---|
| BMW (most modern) | M14x1.25 | Conical 60° or Ball R13 | 140 Nm (103 lb‑ft) | 17mm hex |
| Porsche (991/992/718) | M14x1.5 | Ball R13 | 160 Nm (118 lb‑ft) | 19mm or spline |
| Ferrari / McLaren | M14x1.5 | Special ball / conical | 130–150 Nm (consult manual) | 17mm / 10mm Allen |
| 3‑Piece Wheel Bolts | M7 / M8 / M10 | Flat / conical | 22–35 Nm (use anti‑seize) | 12‑point / Torx |
| Steering Wheel Bolt | M12x1.5 / M14x1.5 | Flat (specific) | 40–50 Nm | Allen / Torx |
Always use a calibrated torque wrench. Titanium bolts benefit from a small amount of anti‑seize on threads to prevent galling.
We manufacture bespoke titanium steering wheel bolts and wheel bolts to your specifications. Provide thread size, length, head style, and drive. Finishing options include:
Natural titanium (matte/satin) Gold TiN / PVD coating DLC (Diamond‑Like Carbon) black Anodized (blue, purple, bronze) Passivation & anti‑galling treatment

Will titanium bolts gall or seize?
When properly installed with anti‑seize, galling is rare. We recommend nickel‑based anti‑seize and correct torque. Our bolts feature rolled threads to minimize friction.
Can I reuse titanium wheel bolts?
Yes, unlike some steel stretch bolts, our titanium bolts are reusable indefinitely within the elastic limit. Inspect threads before reinstallation.
Do you offer titanium wheel bolts for Tesla or Audi?
Absolutely. We produce bolts for Tesla Model 3/Y/S/X (M14x1.5 ball seat) and Audi (M14x1.5 ball R13). Contact us with your vehicle details.
