Good value and take some stick!!Purchased this set to remove the retaining bolt from a VW Golf wheel bearing hub. Required the 18mm 12 point socket which is on a half inch drive. This bolt was tight, I was standing on an 18” breaker bar and dad was hitting the bar with a sledgehammer. We won and the socket held firm and the bolt removed. Given what we exposed this socket to and the fact the socket held firm can only recommend this set based on our experience.

Good quality spline drive setThe ones I have used seem to be a good quality for the price, have used them with my 1/2″ milwaukee impact wrench seemed to handle the torque quite well, the blow moulded case is quite nice.
