IPC-2221 talks to that question, lead diameter to hole size and its focus is solder joint formation. Sorry, my copy is out on loan. But connectors can be a little tricky. Some of them rely on the hole help keep them vertical. Be sure to look at the application notes for the connector as well.

Subject: [TN] Hole size Standard for Plated thru-holes

Hi everyone,
 
Does anyone know of an IPC standard that will tell what a plated thru-hole size should be depending on the diameter of the component that will be inserted. Example would be a pin header, or a certain wire size.  Basically, how much bigger do you make the hole to accommodate the size needed so that you will get a good solder joint, and designed well for manufacturing.
 
Thanks,
Jim
