    I'm surprised this is being debated at all. Production car parts typically have a high margin of safety with oversized bolts. There are applications where even a torque wrench isn't accurate enough, like building race engines for NASCAR, F1, etc. The technician measures each bolt with a dial gauge, writes the length in a chart, and tightens the nut until the bolt is stretched to 75% of yield strength. Here's a $200 ARP bolt stretch gauge for ya:
