Any one go a tap set to re cut threads to put a hali coil into plastic. long shot but I thought I'd ask.I think It would be a m3 left hand thread.

Paul - i got a set of these from a car spares place in Barnsley. Don't think it's quite what your after but can bring on friday if you want. Smallest has m3 left hand thread but its tapered.

Fill the broken plasic thread with super glue, let it dry then screw into it, bit like plastic threadlock!
