It's a 4mm pin, with female threads on each end, and features a tiny button head cap screw threaded into each end.

  I see dual barrel bolts
  
  architectural sex bolts(they have a head on one end & are hollow.
  
  coupling nuts(but your looking for a pin)
  
  binding post with slotted screws, like a partition bolt.
  
  female round standoffs, all SAE no metric. I think thats as close as your describing.

  Maybe a Chicago Screw, commonly used in holsters and rigs.

  That's what I was thinking.
  
  I believe the technical name is a binding screw.

  Captive pin. Many uses. I have 18k gold ones that are used for Tie-bars. Goes thru two holes in your collar and under your tie, for formal occasions.

  Chicago screws are usually only threaded on one end. Hopfully he will get back here and tell us which it is.

  Standoff.
  The button head cap screws are a separate item.
  Try a good hardware store or find someone having a small bench lathe.

  I vote for standoff too. A Chicago screw has a male and female side. Depending on length of the grip (shaft/pin length) is how much they will separate to pieces while still holding them together.
  
  A standoff, however, is used when you want to hold wires away from hydraulic or fuel tubing. The base or stand is secured on a pad (non abarasive) on the tubes with a wrap type chord. Think zip-tie with slots. Then the same chord is wrapped around the wire bundle and it's holding the other base and that is screwed onto the standoff pin. That's how we do it in aviation, anyways. The wires are then held off the tubing to prevent chafing.
