Likely it's just a "standard" 14 gauge nipple for a 2mm diameter spoke.
IF one came entirely loose, your other spokes may also have loosened and the wheel needs to be PROPERLY tensioned to prevent it from happening again.
Machine built wheels can have very poor average tension. I bought a cheap front wheel once and 1/2 the spokes had about 1/2 the proper tension. It was quite true, but still a crap build.
NDS rear?
Yes, that's how the bike came. But I tightened them all up. Unfortunately, I haven't kept up with it over time, and that one must've come loose again.
Turns out it's a 12 gauge spoke, so pretty beefy.
