I made some new adjuster bolts from threaded rod with S/S cap nuts seized on. I drilled the forward end to take a small split pin.
The originals have a small screw and washer in the end, presumably to stop the bolt falling out? But as you say, if they are only slightly loose the end caps will turn and go straight into the sprocket nuts!!!
Might re-make them in Ti one day.
