  2. OEM are M4 fine pitch. Lots of after market use regular M4 with "normal" screws.

  3. Got a set from CT moto. Look identical, good finish and cheap.
     
  4. Thanks for the above guidance. I have gone and already ordered some bog standard M4 off fleabay before seeing your post @nelly. Not sure, but my poor memory is saying to me that maybe last time I changed the wellnuts I did screws and nuts, so maybe I have standard M4?

    Will take one of the screws to work tomorrow to see.
