Grayghost, we used to have stamping presses in our plant that were held together with threaded rods that anywhere from 8" to 12" in diameter. It was impossible to torque them tight enough to stretch them the required amount with any kind of equipment we had, so per manufacturer's orders, they were heated with a torch until red hot, then a wrench hooked up to either a truck or a crane would tighten them down. When they cooled, they contracted, creating the needed torque. That was some serious torque stretch!
