Car owners, listen up - these Gorilla wheel locks are your first line of defense against wheel theft! This set includes 4 acorn-style locks with a matching key, designed specifically for 12mm x 1.50 thread size vehicles. The security pattern is on the outside, making it impossible to remove without the special key - thieves can't just hammer a socket onto these and call it a day. Made from case-hardened steel with chrome plating, these aren't just secure but they also look great and resist corrosion. The 13/16-inch hex size works with standard tools (except for the special key pattern, of course), and the 60-degree conical seat fits most modern vehicles perfectly. At 1.40 inches overall length, they're proportional and won't stick out awkwardly from your wheels. Gorilla takes quality seriously - they control every step of manufacturing to ensure these outperform cheaper alternatives. Installation is straightforward: just replace one lug nut on each wheel with these security locks using the included key. Keep the key in your glove compartment or at home, but definitely not in your car where thieves might find it. Whether you have expensive custom rims or just want peace of mind about your factory wheels, this affordable set gives you serious protection without breaking the bank. Your wheels will thank you!
