This is an extremely well made wrench. The application that this tool excels at is removing nuts on threaded rods such as battery hold down clamps. You don't need several sizes of this type of wrench because a ratchet and socket will work as well or better for most jobs. I deducted one star due to the length of the wrench. It may be too long for some applications. You don't need a lot of torque for a 10mm fastener so a shorter version would be more practical.
How hard can a 10mm nut be to take off that I felt the need to spend the much money. I feel violated. I blame craftsman and the other co. for moving overseas to save a few bucks. This country is circling the drain on all fronts. We All did to yourselves. Viva snap on
