has happened twice on mine. I now have a baggy of screws (OEM) and check after each ride and even ride with one in my tool kit. I'm on a Comp 19 (alloy) with a Fox coil (2021).

What screw (OEM) do you use? Same as original or different?

Loctite relies on a chemical reaction with the metal which is fine with steel/iron /copper etc but both aluminium and Titanium are largely inactive so you might be advised to prime ( loctite 7649) the bolt before using a blue Loctite ( e.g 222). If you decide against using a loctite you will need to apply anti seize to the bolt.
( personally I have no issues using blue loctite on ally screws/bolts without priming on most fixings on the bike. I do not use it on cranks/pedals/cassette nut/hub axle locknuts etc.)

Where did you read that Loctite 222 does not activate with aluminum? LOCTITE 222

my understanding is that Loctite requires an active reaction with the substrate to be fully effective. Inactive substrates like Ally and titanium therefore need to be primed. without the primer the loctite will still "set" whilst in an environment without oxygen so will do something to prevent the bolt loosening, but it does not form a bond with the bolt like it would with a steel bolt and "lock" the thread until sufficient shear force is applied to break that lock.

Ordered a Ti set from BetterBolts, but don't know how long that will take so also called RaceCo and was able to just purchase a lower bolt as I've managed to partially strip the head with my torque wrench when flipping the chip.
