My personal rule for torque-wrenching small allen screws (once I know threads are clear) is "pinky pressure".
I turn the allen wrench until it *just barely* runs into resistance. Then I put my pinky on the wrench and let some of the weight of my forearm (no pushing) tighten it up. Should not ever be stripping allen wrenches in K3 RF/AF knobs. The replacement knobs I got for the flawed early batch that came with my K3 have been just fine. 73, Guy.
