Please can someone tell me what this screw thing is called (drawing attached)

[Tom079555]

I have had to draw this because I dont know the name of it to google it.

It's basically a flat ended screw, but it screws into a tidy cap end.

The screw can be tightened into the cap end, or the cap end can be tightened into the screw as it also has a screwable head

I'm just looking for somebody to identify this.

Thanks!

PS: It is not a nut and bolt.
