With the most recent generation of the Schallers, I would not know where to put loctite. The pin you screw into the body of the bass is a single piece and the screws finally stay firmly in place. On the assembly that goes onto the strap, you have a hole in the ring that allows to insert an allen key or small screw driver to tighten it even harder, then there's the grub screw to make sure nothing moves. I put on new S-Locks on two basses and two straps about half a year ago and nothing moves there.
