McGard Wheel Lock Bolt Set - 4pk. (Cone Seat) M12X1.5 / 21mm Hex / 18.2mm Shank Length - Chrome

If you're looking to keep your wheels secure on your 2008 Saturn Astra, this set of four cone seat wheel lock bolts from McGard is a solid option. These aren't just regular bolts; they function like standard lug bolts for installation and removal, but require a special key tool, making it much harder for thieves to take your wheels.

McGard makes these locks in the USA and EU, and they're known for being an original equipment supplier to many car brands. The steel collar on the key helps guide it into the lock pattern for easier installation and removal, and the computer-generated key designs mean there are countless unique patterns. The narrow groove on the lock itself is designed to resist common removal tools. They're made from fully machined, through-hardened steel for strong security, and the chrome plating offers a good finish while resisting rust. The bolt stem also has a dacromet coating to meet OEM standards.

This set is designed for use with wheels that have a tapered seat, whether they're steel or aluminum. You get four wheel lock bolts and one unique key in the package.
