Pin, M3x12

The 3mm diameter fits perfectly in my lathe tailstock alignment holes, no slop at all. Each pin in the pack has clean, uniform edges that slide in smoothly—exactly what I needed for doweling two small steel plates together.

I've been using these pins for jig alignment on my mini lathe, and the 12mm length is just right for the through holes I drilled. The 3mm diameter slides in smoothly without any slop or binding—exactly what I needed for repeatable setups.

The 3mm diameter fits perfectly into my mill's indexing head holes without any slop. These pins are precisely ground, making alignment work much easier than using random hardware store dowels.
