The type and size of the bolts in the new 128 kit


Could someone please tell me the type (hex? Star?) and size of the bolts holding the new 128 grid kit together? I have just had a wooden enclosure machined but don’t seem have a tool that fits.


1/16" hex wrench

the screws are 4-40 thread

Marvellous. Thanks. Google tells me that’s 1.6mm in new money :slight_smile:
