This lug key provided the necessary security and strength for my automotive needs. The 12 spline design locked securely onto my lug nuts, and the durable steel construction held up to the pressure and torque required for installation and removal. One con was that the larger size may not fit in smaller storage spaces..
I ordered this to replace a missing truck head I bought. I took it to my local dealer to change tires and this socket worked fine with their impact wrench. I will say that determining the right size can be a bit of a challenge. They come in 11/16" and 13/!6" sizes, so make sure you measure or have your lug nuts measured (preferably with an accurate caliper) before ordering.
