Yes: the acceleration rate of a torque wrench is almost zero, while that of an air wrench is substantial, and it's applied the same way a hammer-drill is, in bursts until the nut starts to turn.
In a previous life as a motorcycle- and occasionally car-mechanic, the order was
* start with a long wrench, * add penetrating oil overnight and repeat, * curse loudly and add heating nuts with a torch and cooling with water. * Failing that, buy some new nuts and cut the old ones off with the cutting torch and a cold-chisel.
Before you get to the cutting torch you could try a nut cracker/burster/splitter. https://www.amazon.ca/OURANTOOLS-Splitter-Separator-Removing-Damaged/dp/B095VXSP9S/ref=sxin_15_sbv_search_btf?content-id=amzn1.sym.c49f1e2d-cd8c-49f3-bcdf-e906d6356864%3Aamzn1.sym.c49f1e2d-cd8c-49f3-bcdf-e906d6356864&cv_ct_cx=Metal%2BNut%2BSplitter&keywords=Metal%2BNut%2BSplitter&pd_rd_i=B095VXSP9S&sbo=RZvfv%2F%2FHxDF%2BO5021pAnSA%3D%3D&sr=1-1-5190daf0-67e3-427c-bea6-c72c1df98776&th=1 I have used them in the past on stripped nuts. -- Alvin Starr || land: (647)478-6285 Netvel Inc. || Cell: (416)806-0133 alvin@netvel.net ||
