Torque Wrenches

Ferrari first used a Goniometer back in the 80's to tighten head bolts. Basically it's just a device to precisely spec/measure how many degrees a bolt is turned once a certain, very minimal" torque is reached. Pretty much just ensuring the bolt head is "bottomed" This is common now with "torque to yield" bolts but back when Ferrari first did it, the bolts were "standard" bolts. The process produced a more consistent tightening than a torque wrench and does away with the issue/difference of wet/dry.

Here's a good video on the process:

This method - often referred to as the "part turn method" is a common procedure in the construction industry.
It does though, require a calculated "degrees of turn" based on the bolt's length, diameter and grade. When calculated, it is a superior method to torque as Mike has suggested.
Its genesis came from the extremely variable friction when tightening galvanised bolts/nuts.
Its methodology is robust and applicable to all types of fasteners.
