Pressed thumbstud

I am planning to build a folder with a pressed thumb stud and I remembered to ream to a size .001-.003 under 1/4" but I don't remember seeing if it mattered whether the stud is press before or after HT. Anyone have a thought on this?
 
If you can get your hands on a copy of Machinery's Handbook, it should tell you the tolerances you need. Chris Reeve Knives presses their Sebenza thumbstuds in after HT, and their tolerances for this are something like plus or minus 0.0002 (to prevent the blade from cracking above the hole).
