3/8 24From the ad….
”did XRF test the plate, but my machine just tells me its aluminum. I do not know concretely if it is 60 series or 70 series, but the XRF test does tell me it is one of those. The holes ARE able to be tapped at will: With a sharp cutting tool: However, the plate will arrive without any holes tapped. You can tap the holes if you wish for use. A (M10x1.5mm) tap cuts very nice clean threads for further bolting.”
So, if it won’t work as advertised I’ll have to decide if I’ll send it back or use it for something else.

Will work for my purposes.

Great – now I need another box of fixturing bolts. It does look like 3/4-24 is the way to go, you'll probably warp the plate before the threads fail.3/8 24

You'll like them; I dedicated a HF caliper for this task and modified the box so the "points" don't have to be removed:I went off the deep end this week (wife is up north with the grandson and I memorized the CC number). Two purchases has me feeling like I'm getting away with sumpthin:
- After 40 years of doing the math in my head, I finally broke down and bought a used center line attachment for the clappers! Now without thinking I can measure the distance from one hole to the next as long as the holes are at least .375 and no more than 6" apart and the hole diameter is .375 or less. $20 all in
