Beware of idiots
Your caliperfexion studs are a good example. You provide the ARP and a recommended torque value. Well done.The nut material would indeed have little impact. It is only the first few threads of the nut doing the bulk of the work anyway. The issue is, as was mentioned are the variables. "Lubricants" can vary wildly. Note what happens when anti-seize is used.
And here's a good one with respect to torque, "an indirect indication of tension." It is tension that causes the bolt to stretch and thus provide clamp force. And the biggest variable is indeed K which is exactly what we've been discussing.
