[brote]

I have three, a 1/2" and 3/8". The 1/2" is a Craftsman "click" style and this one takes care of the big stuff (torquing Heads on cars 20 - 150 lbs.). The remaining 3/8", one is "click" and is 10 - 75 lbs. and one is a bar style with "In lbs". I would say I use the 3/8" the most especially the " Inch Pound". There are torque specs for most bolts and I try to do everything using these specs.
