The Butzi Pro Kit anti-theft security bolts offer protection for your car's aluminum wheels. Made from high-quality stainless steel with excellent durability, these bolts feature a unique Type-HH 1/2 UNF tool-key that ensures only you can remove them.

Their installation is simple and can be done without lifting the car or going to a workshop. Follow these steps:

• Unscrew your standard bolt, one from each wheel.
• Check that the security bolt is the same as the car's bolt.
• Place the security bolt by hand and screw it clockwise.
• Place your lug wrench over the key-bolt and tighten all bolts.
• Store the key-bolt with your tools.

The set includes 4 security bolts and 2 unique key-bolts, with a total of 6 pieces.
