Enough that I don't know which is true and wouldn't trust anything I see anywhere unless it comes from someone who actively uses them all the time in critical applications. There's a chance they don't work at all or make things worse, and a higher chance there are only specific situations or methods to effectively use them. It seems to me your configuration needs a nut so use a jam nut or nylon lock nut. No threadlocker (unless it's superglue) because there's plastic in your assembly. | |

That said, I'm not super confident of split-lock washers in terms of effectiveness, especially in smaller sizes (M3, M4). For more important situations we used belleville, serrated belleville, or even wedge-lock (aka nord-lock) washers ($$$). Also, IME, flat-washer vs no-washer does noticably reduce random self-loosening. I'm not sure the mechanism of it. Maybe it gives a more consistent relationship between torque and axial load on the screw. | |
