I always place thumb on box end of wrench no matter how long wrench is and is guaranteed to torque same on all nuts or bolts and won`t over tighten,works on long or short handled ratchets too.Old indian trick I learned from an old head when I was a railroad machinist for 12 years in 70`s and 80`s.When it has to be precise use torque wrench.Not trying to be smart alec,just passing on some knowledge that works anywhere but especially where you have previously skinned knuckles.....
