I have a dedicated Anvil-30 with CFT-34 tripod, but I had Swarovski CT tripod that I wanted to mount a Anvil-30 head for sighting in optic fitted pistols; same issue as OP mentioned, any mount would unscrew from tripod stud as one manipulated the firearm. So, I milled a slot in the Anvil to fit a simple fastener to engage available thread mounts in the head base of the tripod, apply Aluma-black to milled surface. Rotation problem solved.
