In the auto industry, they use bolt stretch calculated in a lab to approximate a certain bolt torque. Piston rods are the only place you can actually measure the stretch and is the best way to install your bolts. Very few (I can't think of one, so I'm sure I'm missing a couple - oh wait, the brakes!) bolts in a car are required to hold under the perpendicular pressure that a BCG gas key bolt is. As to the calipers on brakes, their primary force is still linear, and those bolts are always much larger than they need to be, don't ask how I know. Also, most bolts in cars hold a linear pressure and have several other points of contact for a particular part. One nice reason to stake even if you Red-tited is to visually check if the bolts have moved, though they won't... ever. I've used Red Tite in racing engines for years... less and less as I learned what parts really need it, and what don't. It makes taking them apart again a real pain. Thank the Good Lord for copper anti-seize!
