Hey, i've been looking around, and can't seem to find much. how do torque wrenches work? Regular ones, electrical/hydraulic ones, and the one's that check torques (either mechanical or electrical). Any info that can be given would be great..... actually, another quick question on that as well, at the factory i'm working at i have to do torque audits (use big wrenches to check torques on different parts to see if they're up to spec), do they have an electrical version of this to use? Thanks a lot guys!
