Just put two wrenches on and make sure they don't move. If I had done this it would have saved us over an hours work rechecking everything after we found a slight seep. Please keep in mind that them not being tight is an anomaly and I probably got the one set in a run of 100 that wasn't tightened properly when assembled.

Z1 was quite surprised and apologetic about this so I'd guess the likelihood of it happening to many others is pretty low. Just better to check before but be careful as over tightening them is very bad and will make them irreparable.
