T/C Hawkens under rib thread???????

If I remember correctly it would be 6-40 thread. It’s been thirty plus years but I think that is correct.
Its been a long time since I re-barreled one of those, but for some reason 5-40 comes to mind.
I could be wrong.
6-48...all T/C screws that go into the barrel are all the same size. Under rib, rear sights, ramrod retaining spring, thimbles.
If you have a screw from the rib, then measure its diameter then find a machine screw chart and look for the screw diameter on the chart. This will tell you what screw size it is then you will track down its thread pitch with a screw pitch gage or by guessing
. If you don't have a screw then measure the I.D. of the threaded hole and add 0.032" to the measurement and this will give an approximant diameter of the screw - not as accurate as measuring the screw but it will get you into the ballpark. To get the "idea" of the thread pitch get a toothpick and melt some wax onto it and press it into the side of the threaded hole to get an impression of the thread then you can get a better "guess" of its pitch. OR call the company that made the rifle and ask them
