Can anybody tell me how to work out what size bolt I need?

It's for the 4 that hold the circular disks to the spindle in the throttle body. Left my brother the simple task of stripping it down after I removed it and the plenum ready for cleaning and he managed to round 2 of them rage

They are 4mm diameter and 10mm long (from under head to the end), round cheese headed with a phillips type head but might be metric fine thread, i dont have a thread guage to check.

Dont forget to use Studlock or Locktight when reassembling

Thanks Norman.

I've ordered a thread gauge this morning. So will double check in a few days.
