most of what i use is 1/2in drive for lbs, and 3/8 for in.lbs. most of what you will deal with will more then likly be from 35 to 90. this puts you in mid range for your wrench. after using it i allways reset the wrench to 0 so that their is no pressure left on the spring sets. their will be a few requirements for torque over 100 but not very often. take care
