To ensure the security of your vehicle's wheels, follow these steps carefully. First, use a suitable wrench to remove the existing lug nuts from your car's wheels. Once all the lug nuts are removed, take the anti-theft bolts and insert them into the same positions where the lug nuts were previously located. Make sure each anti-theft bolt is properly aligned and seated. After inserting all the anti-theft bolts, use the provided wrench to tighten them securely. This will help prevent unauthorized removal of your wheels, providing an added layer of security for your vehicle.
