What value do you pick in torque range specification?
When the service manual shows a range of torque values, say 32-50 in-lbs, for a fastener, which value do you guys pick? Do you choose the midpoint value? Or the highest value?

I usually go for the top value. I'm work on boat engines and usually they only give one value. I also have my torque wrenches calibrated regularly since I work with them daily.
If going into aluminum that has been in a salt enviornment I will go lower.

i go 5-8 lbs below the highest value

I always do the high end value. Then when I check the critical fastener list during the service interval, I set the torque wrench for the low end value. If there is a "click" then it is all good.

the fact of the matter is, that you are supposed to torque the fastener twice, first the lower number and go back to the higher number. this is a specific value given to tighten, why would the manufacturer give you a spread for you to choose? why would they give a critical value, for you to have error in your torque wrench? this has been discussed before, and never been confirmed either way. I went to an automotive college, and numerous factory schools and have always been taught this method. do what you want, you all will anyway, but the correct method is described above. will it make a difference? no, but most critical torques are now given in angle rotation, because of stretch bolts, torque to specified single value and then turn usually 90*. Again, most torque values are there, but most are not necessary. there are some critical torques, head bolts connecting rod, main brg bolts, but everything else is "just before they break" if you're not used to tightening bolts use a torque wrench, but a little common sense and a sense of feel will accomplish the same thing, I am not getting into any torque arguments!!! this is discussed as much as oil!!!
