I’ve spent quite some time looking for 2mm x 40mm self-tapping coach screws, and I’m really not finding many coach screws smaller than M6, or 6mm. Does anyone have a suggested source?
If it matters, I’m in the US, in Maryland, but I’m quite willing to order from any (reasonable) source.
I’m using 3mm x 40mm screws for wood (e.g. Spax), which you will find almost anywhere. You just need to drill out the holes in the toolhead and the arm a bit (e.g. to 2.5mm).
