Found bolt on trail

I found this on The Attic while doing my own repairs. Not a style bolt I have seen yet, so if it’s important, fear not, I have your bolt. If not important, I’ll toss it. Can anyone identify its use? Looks similar to a pedal stud but twice the size.

Looks like the bottle cage bolts on my older specialized.

Fair enough! Not overly important then. Will likely just end up in my bolt bin if no one needs it.
