Need Delta 23-197 Grinder Help Pease...

[Derek Arita]

I'm looking for replacement arbor nuts for my grinder. The replacement M16 LH nut is there, however the RH nut is listed as an M12, but I'm sure it's an M16 as well. What gives? I wouldn't bother with erplacementparts for simple nuts, however these are flattened on one side, so it does matter.

So the manual says its an M16 yet the vendor has that part number as M12. I wonder if they would measure it to see if their listing is a typo?

Just measure the outside diameter. Huge difference between M12 and M16. Should be able to use a tape measure to figure that out.

Use a metric socket to measure with.

From what I can tell, they really are both M16. I hope it's just a typo, cuz I ordered some. We'll see...
