To get the final torque AND stretch on the bolt, you tighten the bolt a given number of degrees of rotation. This is what the torque angle guage is for, accurately measuring the degrees of additional rotation (typically accurate to a degree or so). The Reason For Not Re-Using Stretch Bolts.
T. rex had a mouth full of serrated teeth; the largest tooth of any carnivorous dinosaur ever found was 12 inches (30 centimeters) long. But not all of the dinosaur's teeth served the same function, according to a 2012 study in the Canadian Journal of Earth Sciences.
This variation in tooth shape sometimes makes it very difficult to assign isolated teeth to a particular dinosaur species. Tyrannosaurus rex is the reigning king of tooth size with the longest recorded tooth being 12â long. This measurement includes the root of the tooth with the exposed portion being around 6â.
