Possibly Avistar ARF Assembly Prob???
I tend to use something to hold it when gluing a stab on with epoxy. Makes it so I don't have to re-measure and risk moving it. That is actually the one things a T pin is good for.
If it bugs you and you want to fix it, you can get it off. Use your monokote heat gun and heat the epoxy and it will come off. Don't force it though, you will break it.
As stated earlier, you won't notice it anyway. I wouldn't mess with it.
