I know this is similar to cam or dowel type fixings, and I have searched extensively for this part, but does anyone know exactly what type this is? Specifically the silver section, as I have enough of the screws/tighteners left, but I need more of the fixings.
They are not quite the same as generic cam/dowel fixings as they have this cut out for the screw to go in and hold them in place.
Any ideas would be very welcome.
If you're trying to completely change the treading on a nut or bolt with a tap and die, I don't think that's going to work very well. You may be able to get a new thread pitch, but it will be interleaved with the existing one, and all you'd be doing is weakening the thread material.
If you need to simply fix some mangled threads, then have at.
If you're looking to cut your own bolt threads, you will probably want to start with unthreaded rod. Although, as Cathode mentioned in the comments, if you have hardened steel rods, you're in for a lot of frustration and not much success.
I suppose you could chuck the bolt into a lathe and carefully (very carefully) slice the existing threads off to give you an unthreaded rod with with a nice bolt head, but then you'd have to grab a box of nuts of sufficiently small size that once you ground the threads out of the inside the resulting diameter would match up with your newly "skinified" bolt stock & you could rethread those.
All in all, I'd head to the local big-box and grab a box of what you need for your current project. You'll have some spares for the next project, and will, eventually have a few dozen of everything lying around that you can't find.
A few options, in no particular order:
Take the batten off the wall, drill pilot hole, replace. Then you can use whatever size screw is necessary.
These plug into an existing drill and let you get into tight places.
Not as strong, but depending on the application may be an easy way to accomplish the goal of preventing shelves from coming out
Use a couple small angle brackets to drill into the bottom of the shelf.

After more reasearch, it appears to be flat pack furniture assembly cam and dowel, more common on newer Ikea furniture. Try calling Ikea or checking online with them about replacement parts or extra parts. Or perhaps contact the manufacturer of the connector.
