This is a really beautiful and functional nut. The "star" loop/shape also requires a special socket (comes with nuts) which increases the security of your wheels and makes nut installation and removal much easier. The special socket provided is a deep socket that fits snugly over the nut and is tightened with a standard socket wrench. Nuts have correct cone head required for aluminum wheels, repeated torque after 20-30 miles was minimal, my truck requires 150 ft/lbs after initial wheel install and about 30 miles. Really good product.
