M3 x 0.5, 5mm length, 6mm button head, T9 screw post source?

Ok, here's one that I'm having a hard time finding a replacement for .....

M3 x 0.5, 5mm length, 6mm button head, Torx9 screw post?

I guess it does not need to be torx.

Edit: I think there are other terms for screw post, such as binding post, or barrel bolt
Second edit: forgot to say, the o.d. Of the female portion of the post is 3.91mm

@speed and @M6. Unfortunately McMaster and fastenal only have these in SAE. Not metric. And although I think I could substitute an OD 5/32" barrel for the 3.91mm barrel, they only carry down to 1/4" size.

@piguy. Yeah, I can find m3 .5 screws, but I'm looking for this type called a binding barrel by mcmaster:

In the above dimensions.

I also found out these can be called '*** bolts'.

If they don't have it, then you'll have to go to asia.
