Frequently Asked Questions

Will these fit my wheels without needing adapters or cones?

The 50mm extended length and conical seat design work with most modern aftermarket wheels. Test-fit one nut on your wheel before committing the full set—some deep-dish or barrel designs may need a seat ring, depending on your specific wheel.

How do the lock nuts work?

Each lock nut has an internal nylon insert that grips the stud threads and resists loosening from road vibration. They also deter theft since they're matched to your key. Replace them if they spin freely—the insert wears out over time.

Do I need to torque these to a specific value?

Refer to your vehicle's service manual for the correct torque spec—usually 80–120 ft-lbs for M12x1.5, but it varies by platform. Use a calibrated torque wrench and tighten in a star pattern to ensure even clamping.
