Review on Mishimoto MMLG-15-LOCKBL Aluminum Locking Lug Nuts M12 x 1.5 Blue - Durable and Secure Wheel Fasteners by John Bennett

So many people here can't read the description! The lock is designed to work with just 4 grommets (1 per wheel) and the other 16 are a standard key size. You can tell the difference as standard locks have 6 sides while nose locks have 7 sides. It's an ingenious design as they all look pretty much the same and don't have an exaggerated lock nut like most traditional kits. If someone tries to remove your wheels, they can't remove them all with a standard wrench. They are light but very durable! Buy them with confidence and enjoy them.
