All makes sense except for one thing. A 6-point wrench or socket is by far the best choice if you are afraid of rounding off the head of the bolt (or nut). The only reason for 12-point wrenches is convenience (twice as many places to land on the head of the bolt). Half of the points are not used at any given time. The surface that makes contact on a 6-point wrench is effectively 100%. In fact if you round it off with a 12-point wrench, go back at it with a 6-point. You might need to use some persuasion to get it over the rounded corners but if you get it on you will still have a lot of useful flat area left to get some torque on.

Ratcheting closed wrenches are a pleasure to work with but for high torque the ratchet can possibly get damaged.. I'd go with a plain ol' forged one piece wrench. Depending on the angle, an offset wrench might help as well: <http://www.amazon.com/Point-Offset-Metal-Wrench-Spanner/dp/B0087ZU6DQ> http://www.amazon.com/Point-Offset-Metal-Wrench-Spanner/dp/B0087ZU6DQ as mentionned before the tighter the fit , the straighter the wrench, the less chance of stripping the bolt. Also, you might want to see if you can slip a piece of metal pipe of the the other end of the wrench (A "Cheater" pipe) to lengthen the lever / increase mechanical advantage, sometimes that makes an "Impossible" job easy. Finally, don't forget to coat the stud with anti seize compound when you re-assemble to make the job easier next time. Best of luck -Francois Rivard 1990 34+ "Take Five" Lake Lanier, GA
