If you don't have a torque wrench that does inch-pounds, get one. I tried to extrapolate down from the lowest setting on my foot-pounds torque wrench and torqued off one of the transmission pan bolts on my other truck. Lesson learned the hard way. I now have a Snap-On 1/4" digital torque wrench.

80/12=6.6 ft/lb
My 3/8" wrench goes down to 25 in/lb or 2.08 ft/lb. If your wrench doesn't go down to 6.6lb or 80nm then you need to get the proper tool for the job. I work with a lot of 6, 8 & 10mm bolts in high performance motors so I know the importance of proper torque.

Same here... building race motors I have many unusual and uncommon tools. I can hear it now... "what's the purpose of 50+ small blocks of metal in a really nice box and what's this stick with a dial in it?"

And that is why an inch pound wrench is needed. The foot pound wrench on the lowest settings is still too much for these small bolts. Just consider the ft pound wrench is 12 x more course than the inch pound. In other words, if the ft # wrench is off by 3 it equates to 36 inch # or roughly half the total torque on these small bolts.

Oh, my bolt head just snapped off. Plink! That was it. I'm not much of a technician when it comes to stuff like this so I took it to someone to extract the bolt, dress the threads and put a new bolt in properly. Expensive lesson. Inch pounds matter.
