Funny you mention that. I read an article last week about busbar connections in panels. The writer found that uneven torque from a regular driver caused hot spots and eventual failure over time. It wasn't about being loose, but about the inconsistency. One terminal at 8 inch-pounds and the next at 12 makes a real difference. That sold me on using a torque tool for anything carrying a real load. It just takes the guesswork out.
