i just go by the feel of the bolt but like said by homer i hate the click type too . i use the click type on big bolts ( chevy rod caps , mains , rods . heads ) but you always want to step up to the final 50 ft-lbs , or inch lbs by three torque settings like ten twenty thirty #'s then hit them one last time but i have broke bolts with a torque wrench whats why i wont use one i like to feel the bolt and threads , on heads i watch the gasket , i always dip the bolt in a little oil if the threads are alum,, and i always use loc tite on bolts and or nutts that are non ferrus ...
only good for 10 to 50 ft-lbs., any lower and it gets messed up." i totally agree i have used the click type then used the needle one to check it and the click type was showed the bolt too loose ,,,, happy new years
