I think it might be like "mechanics feel" they talked about directly in the book zen and the art of motorcycle maintenance.

You get enough experience and you can turn a bolt or screw and tighten it to stretch a little.

Not too little (doesn't hold parts together and/or can come loose).

Not too much (uneven tightening or snap/strip something).

Just right (torque wrenches make this precise).
