Cinelli 1E stem wedge bolt

I have a bike that a friend of my son's bought that I'm building up for him. It came with a Cinelli 1E stem on it, which I am trying to use. The wedge bolt was replaced with a std. hex head bolt, instead of the recessed allen head bolt. I would like to replace this with a recessed bolt. I tried one from another no-name stem I have laying around, but it wasn't the right diameter/threading. Is the Cinelli I have one that takes the oddball 7mm bolt? And used a 7mm allen key? Any suggestions?

Take the hex head or wedge to a real hardware store or fastener dealer and they can tell you what the thread is.

If the wedge is Cinelli/Italian threading, you will need an oem bolt or rethread the wedge for the substitute bolt.

I would take the wedge and bolt to the hardware store, get a grade 8 bolt to match your bolt, cut chaser slots and rethread the wedge with anti seize.
