hello TBolt-this tool is a lifesaver you flip the sockets from torque to speed and it has plenty of height and width to handle most any job I would say honestly 14 mm and under without then be breaking etc.

It is so handy that not only I have one I'm currently using in our main toolbox but I'm going to buy one for each motorcycle and since I never ride alone I will attach and 8mm 10 mm 12 mm to one T wrench but the other one I will attach 13 mm Phillips head and a spare 10 mm just in case I leaves the first one :-) no joke everyone knows 10 mm is like a glass of water on the desert when you're in the middle of nowhere.

I also am going to take my 10 12 mm 13 mm 14 mm wrenches to the long side of this French and then put it in my toolbox on my motorcycle right next to my spark plug.

Excellent tool!

Sincerely;

Philip
