Love all of my Grey Pneumatic sockets! Best money I've spent in a long time. These updated versions also come with the size stamped into them! Thanks for listening to us GP! Now you don't have to worry about trying to determine the sizes on super worn out sockets (if these suckers even wear out!). Being Cr-Mo, should be able to use these on 1000 ft/lb impact wrenches with no issues.
