which number threadlock for spider arm bolts please

[Ojustaboo]

Hi, I have a new spider arm for my Samsung Ecobubble on it's way.

On removing the bolts from the old one, they all have blue threadlock on them.

Simple I thought, but there's tons of different numbers out there. Can I just buy something like Loctite 2400, 243, 248?

The water will wash over these bolts, but I presume as they will be firmly ion the holes, soap etc wont affect the threadlock?

 

Many thanks

I couldn't give a definitive answer, but I would have thought if you put loctite on the threads and screw them in then the water wouldn't get to it and the loctite should hold the bolts.
