The ball headed adjusters on the rockers are M6 FINE thread (0.75 pitch I think?). So please don't tighten the lock nuts like a gorilla!
I've just been having a go at lightening some used rockers I got from NLM as an experiment (OK - only managing to lose 3 gs or so but nice and shiny
![Wink ;)](./images/smilies/icon_wink.gif)
). I'd sorted through the box to find ones with 'good' thrust pads and decent looking bushes. Some were without screws and the threads have turned out to be OK and so I shall swap in adjusters from the ones off the engine. One complete with adjuster and nut freed up OK. I should have known to leave the one with an adjuster but no nut in the box. The thread is buggered. I suppose it might have just enough range of movement left as an emergency 'spare' (I did have one adjuster strip the thread years ago at a hill climb).
The lock nut only needs nipping up, so leave the half inch drive 10mm socket and tommy bar alone and use a suitable tool!
Talking of which, has anyone tried using Titanium nuts - lightness where it matters (the end), but would they survive?
