in many languages "hand" and "arm" are the same word, or even when they are not in practical use when you say "arm" it includes implicitly the hand. Thinking of it, that's a good example of how something seemingly simple and straightforward could be a nasty trap when translating.

here this is the relevant picture:

not dynamo rotors or rotating gates.

the possibility to tighten anything on your product using only hand/arm instead of both is certainly worth bragging about, and here it concerns "Aerospace anti-loose mounting bolts" - you don't need to hold these bolt with one hand while turning them with the other hand - "anti-loose mounting bolts" are not going anywhere - (they stay attached to main part) they are not going to fall off and roll in some corner where you can't get them out ...

@Daryo Further to my previous comment about guessing:

Or, perhaps it does mean that it can be tightened using just one hand. Should one guess that "arm" is a mistake for "hand"? or that it relates to tightening each arm of the rotor independently? or that it means that tightening only needs to be carried out to one arm of the rotor?

It's essential to try to be aware of alternative meanings, rather than getting fixated on the first one that you think of.

Oh well ... I spotted that you closed the question only after putting an answer!

Which BTW seems to me pretty obvious (having some practical experience maybe makes a difference?), never mind all the puns you can make - you forgot the "One Arm Bandit" ...

Compared to some other "Chinese English" it's not that bad.

HAHA!! Merry Christmas and thanks for your funny note.

@Asker This looks like it was written by the perpetrator of the text in your other question. Does it mean that amputees or people with a cup of tea in their other hand can tighten the bolts? Does it mean that the bolts tighten one arm of the rotor at a time? Who knows?!
