Have just purchased a new SMPC which was sized for me at the shop but I want to make some adjustments and though that this would be simple. However, I now discover that the cheap 'jewellers' screwdrivers that I thought would do the job, don't....
Can anyone confirm the correct size screwdriver required and give any recommendations of which type/where to purchase same?
Thanks

 

I have a precision screwdriver set used for electronics which includes a 1.5mm that works perfect.

1.5mm size will do the job fine
