Dang it.....that makes an angled countersink.  You'd need a flat bottom for the 
flange on the SMA bulkhead connector.  At a glance I thought the depth stop was 
the cutting edge.  Never mind, I'm stupid.  I know nothing.

If there is such a thing as a countersink bit that makes a flat bottom hole in 
metal then maybe that's a way to go, but it doesn't seem to be a simple thing 
to find.

  Here you go.  Countersink the hole with a bit like this.  I should do the 
googling before the answering next time.

    Yes, the plate is nearly 4mm thick. I've seen these on radios before so I 
know they exist but I just
    can't seem to find them.

      The screw terminal you refer to is the threads on the SMA bulkhead 
connector?  I take it you’re mounting it on a thick plate of some kind?  Wow, 
that’s a lot of thread, good luck.

      I'm looking for an SMA to U.FL pigtail that has a longer screw terminal. 
Most I've found

      have ~14.5mm threads exposed, I'm looking for something closer to 20mm. 



      I've search online but can't seem to find anything. Anyone know of a 
source for this?
