I have 2 sets of TC rings and bases , one piece SS . I called TC and they said that they do not sell screws for rings. That you have to buy rings too, I paid $50.00+ for them. , that sucks. They said that they did not no screw size, that sucks too. I like to replace with torx head in SS . Anyone no size and place to but
The person that told you that they did not know the screw size was probably just reading the computor parts screen in front of their face. If you had asked for the custom shop (assuming they still have one) those guys are really down to earth (they even did an off-the-record trigger replacement for me that was ... well ... let's just say it was "perfect")
and they would have told you the screw size so that you could go to Brownell's or similar and just buy the screws you needed.
Here is the link to buy 6-48 in TORX; you just need to know the length or just buy the size you know will be a bit too long and then file them off to fit; it's pretty easy.

each screw separately without loctite in the scope base, tightening it down and making sure that each screw makes the base feel "solid" and tight, ALL BY ITSELF. Then remove it and test the next one; each in it's own hole that it will go into for final. On the final tightening use a little medium strength loctite on the base screws; if you want to, sometimes I also spread a thin layer of loctite along the top of the barrel under the base to help hold it and fill in any tiny voids of metal to metal fit; then after the base is tightened on, wipe off the excess. If done properly you shouldn't have a problem unless the caliber is a "heavy" and then you may need to go to a six screw T-Sob base (I DO NOT mean to open a can of worms here, guys, as far as four screw vs six screw bases.)
