I have found that Loctite 567 sealant not only seals well but makes it very hard to remove once cured (24 hrs). Thread lockers
like the red, are the similar anaerobic materials, but with higher
strength. Green as better wicking and medium strength, not likely what you want. Access the hot link.
I think I would try the standard 567, rotate to the correct position 3/4 past where you show, let it sit for 24 hrs to yield full strength, and then decide. Test with some known torque and if it does not move, then install. The 567 has some teflon so it is unlikely to gall. Just an opinion.
It seems the only other simple choice would be high strength epoxy, but the Loctite might just have better shear strength anyway. The Loctite TDS does not give shear strength, but a breakaway torque several times higher than installation torque.
