M12 Titanium Bolt

Track-grade Grade 5 Ti-6Al-4V titanium M12 wheel lug bolts engineered specifically for BMW and European performance cars utilizing 60° conical seat wheels. Available in shank lengths from 28mm to 43mm in both M12 × 1.25mm and M12 × 1.50mm thread pitches, driven by a heavy-duty internal Torx T70 drive. Each M12 titanium lug bolt weighs just 32–42g—saving ~40% rotating unsprung mass per corner compared to OEM carbon steel bolts, delivering sharper steering turn-in and improved suspension rebound control.

Frequently Asked Questions

Which cars use M12 titanium conical lug bolts?

Classic BMW E-Chassis models (E30, E36, E46, E39, E90/E92 non-M), older European performance cars, and aftermarket tuner wheels with 60° conical seats.

What torque should I apply to M12 titanium wheel lug bolts?

Torque to vehicle factory specifications (typically 110–120 N·m / 80–88 lb-ft). Use a calibrated manual torque wrench with a quality T70 socket; never use an impact wrench.

Can I use conical seat lug bolts on ball seat wheels?

No. Mismatched seat geometry results in dangerous knife-edge contact and catastrophic torque loss. Always verify if your wheel takes conical (60°) or radius ball seats.
