They are genuine Hipshot. The bass is in the shop getting the frets dressed- the guy doing the job has already talked to HS; they advised him to apply red loctite & let it set for 5 hours. I'll be picking it up Monday; we'll see if it works then...
BTW, according to my repair guy, HS told him they've had this issue before & are tooling up to use reverse threads where it will make tightening the string also tghtening the button, if that makes sense(not worded well, blame me

).
