Where can I find those stainless steel dowel pins?

I’d just order some from the FarmBot store but they seem to be eternally out of stock. I can get 40mm stainless steel pins, but not ones with the knurling on both ends. I’ve checked Grainger, McMaster, Fastenal, etc.

Anyone know where to get this exact part?

Do you have a part number for the ones you need? I need some as well and be making some.

I used a 16p nail. . . was a little knarled from the vise, but worked well…
