There are some typos related to the crossbeam screws in the AltMill assembly documentation, specifically on the following page:
On this page, the crossbeam screws are incorrectly labelled as “(with loctite)” when in fact these screws do not have loctite. This instead should read “(without loctite)”.
By comparison, you can see that this is labelled the opposite (and correctly) on the unboxing page where the parts are listed:
If you would like any further documentation, I would be happy to get a picture of the screw baggie for the crossbeams which contains screws with no loctite on them. I submitted this feedback some time ago on the resource pages but never got a response or correction, so reposting here for visibility.
