hmm... Is an m12 near a 7/16 bolt? What is what I used in there and it has some play. So thts why I was wondering.
from looking around a 12mm is .47 roughly. And a 7/16 is .43 roughly. So that would make sense, as there is a little bit of play, well NOT play but room around the 7/16 bolt.
Does it say what the pitch is?
