This is the 3.0mm metric hex ball wrench from Thunder Tiger. This wrench is 120mm long and comes with a silver/gray high grip handle. This is a hex ball wrench which has a ball style tip, which is great for accessing hex screws where you cannot get direct access and have to come in at an angle (ie: engine mounting screws!). The tip of this wrench is replaceable, so if you break a tip you can just buy a new tip and not an entire replacement tool. These are also nice because they have long shafts on them, making them great for accessing hard to reach places (like the grub screw for retaining the tuned pipe on 1/8th scale buggies!). Thunder Tiger wrenches also have a cap on the end of the wrench that will open up allowing you to store screws, buts and bolts inside the wrench if you desire.
