You could buy a fully loaded snap on truck for the cost of the head bolt torquing apparatus car manufacturers use. Torque in steps... nobody has time for that. Run every single head bolt down and torque them all at once.As bob15 pointed out, it's a production line tool. It torques a fastener to a specific torque hundreds of times a day spanning across three shifts. It basically never stops running. People think that Snap-on makes the most expensive tools in the world; they don't.
