Bolt only threaded near head?

Does anyone know if you can buy the opposite of this:

As in a threaded section near the head, smooth at the tip?
Like a kind of combination bolt/dowel... I want to put a through two pieces of wood, securely fastened into the first but able to move in the second.

I had thought about a metal rod acting as a dowel with one hole snug and the other a bit loose, but then how could I ever remove it - the top won't be accessible.

Could you make something up using threaded rod?

file /emery paper /grinding wheel

Sex bolts involve a male and female part that would mate

You could use a bolt that had a thread all the way along and put it in a drill press/lathe and use a file or machine off the first portion of the thread? If I was doing it I would first add a nut onto the bolt to reform the thread end

I never heard of those and was nervous to Google it very interesting but in my case the 2nd piece of wood don't be drilled all the way through to reach the other side.

Filing a bit sounds it might be simplest.

I can't decide if the thread matters or I'm just being a bit anal. I would like the retaining hole as small as possible without any chance of it binding so I thought a smooth rod might work better?

What about putting a sleeve through the wood?

thinking about it more get a bolt 20-25mm longer than you need
then as above and then cut off the extra as that much easier than abrading the end thread

That's a handy tip. I don't have a bench drill or grinder only a hand drill and a vise and various abrasives... To avoid doing a shoddy job, any more tips the best way to do it?
