⚠️ Important Safety Notice
Wheel nuts are safety-critical fasteners. Always use a calibrated torque wrench. Confirm thread direction before installation — do not force a nut onto a mismatched thread. Do not lubricate threads unless specified by the workshop manual. Retorque wheel nuts after the first 50–100 km of driving.
- Clean the hub bolt threads and wheel nut seats — remove dirt, rust, or old thread locker.
- Hand-thread the nut onto the hub bolt — do not cross-thread.
- Tighten in a star/cross pattern in stages.
- Torque to the specification in your workshop manual.
- Re-check torque after 50–100 km of driving.
Check wheel nut torque at every tire rotation or every 10,000 km. Inspect for corrosion or thread damage during wheel service.
- Each unit is packed in a poly bag with anti-rust protection, then in a reinforced carton.
- Suitable for wholesalers, tire shops, and fleet maintenance centers.
- MOQ: sample orders accepted — please contact us for volume pricing and stock availability.
