Torque Wrench Sizes

My 2...

I wouldn't bother getting a 1/4" drive torque wrench. If you are working in this low of a torque range - use a 1/4" screw driver style tool with socket and tighten the fastener to feel. Difficult to over-tighten to the point of stripping threads using this method (i.e. method to tighten valve cover nuts).

For all but the highly unusual (*maybe you should consider a pro) 911 projects - you need 2 torque wrenches: one for smaller fasteners (up to ~ M13 bolts & nuts), and one for larger, higher torque fasteners (i.e. lug nuts). This often leads to buying a 3/8" drive and 1/2" drive torque wrenches.

Ultimately you want to use a torque wrench that has your required torque setting (ex. 22 ft-lbs for spark plugs) in the middle of the wrench's range. For spark plugs I use a Proto 3/8" drive torque wrench that has a 16 to 80 ft-lb range. For lug nuts (~94 ft-lb spec.), I use a Proto 1/2" drive torque wrench with a 30 to 150 ft-lb range.

Bottom line, if you are into working on vehicles - you should get 2 torque wrenches that cover lower (up to ~ 80 ft-lb) and upper (to ~ 150 ft-lbs) torque ranges.

If you run into a project that requires a specific torque setting higher or lower - then you are probably ready to buy other tools as needed...

Good luck,
