Kraton Loctite on servo screw: yes/no?

[bscheife]

New K6S, fixed endpoints and centred servo, but now I have a question: Do y’all use loctite on the screw that holds the servo arm onto the servo, or do you worry about the loctite making it’s way into the servo that way and gunking it up from the inside

Yes.
The tiniest smear of Blue TL on the last few threads is good to do. So the screw wont loosen up and strip out the servos output spline. Yes this is standard to do with metal output shafts. The servo arm gets a lot of torque in this area and can easily loosen. Metal on metal gets TL in general.
Tip: Be careful you don't use a VERY long servo screw. It will ruin the Potentiometer directly below the output gear where the screw goes into.
Let the TL cure for 24 hours before use!!!!!

I use the cheap blue loctite from Harbor Freight on my servo horn screw, as well as a little bit on my wheel nuts. I find it adds a bit of resistance to prevent fasteners from backing out without putting up a real fight when I want to remove them. I use the Loctite branded red stuff on things I want basically permanently affixed, as intended.

242 blue is fine for metal applications but not plastic. good luck

I do not use any on the servo horn. Never had an issue.

Like SRC said I use a VERY small amount of BLUE loctite in servo horn screw. Loctite 242
Ive had the screw losen up on me before with no Loctite

Thanks all around. I’ll try these suggestions

I use blue on my gas airplanes servos. Cars and trucks I don't bother.
