Excellent socket! Very well done. The cover is very tight and definitely protects your wheels. This is a plus if you have expensive non-genuine discs. It fits my torque wrench perfectly with no adapter required and makes it more accurate when tightening my nuts to spec (80 pounds in my case). Another good reason to buy it is the great price. I am very happy with this socket and my key seems happy with it. Keep your instruments happy, boys!
