If the servo has a metal spline gear, you "could" use it but usually servo screws usually don't back out.

Don't use thread lock. Just screw it down good and you will be fine.

Brilliant thank you so much

Just to counter...
I find that most don't use TL with fasteners holding the Arm/horn to the Servo out put spline shaft. I do, but very sparingly. Using heat for removal, if need be. The slightest drop, not even, just a smear is good to do. I tried it both ways. There is nothing worse than stripping your Servo's metal Spline, and/or Arm/horn due to a loosened Fastener. Been there. Years back. So I do use Blue TL in this area. But using less is more. And I usually only use a Socket head M3 screw on my Servo, 99% of the time.
Just me.

I find that servos with Brass output shaft splines ( soft metal) are the worst. I stay a way from those types of servos. They strip easily and snap as well.

You could use an internal lock or star washer as well, my horns have the double side bolt clamps otherwise I’ve used a little 242 blue on the screw with the basic arrma horn.

With clamping arms/horns, they are great, but only if you know the best sequence of tightening the output shaft screw and Clamping screw(s).
Done wrong, I find they can loosen as well. Especially cheap knock off generic clamping arms/horns. I usually even apply Blue TL to the Tiny clamping screw(s). Ever so sparingly.
I want my Arms/ horns to never need to be removed until I am replacing that servo, in the first place. It should be one and done. It should never loosen until then. Short of any great carnage and damage to the arm/horn itself , that is.
