Freaky bolt size, I hate when companies do that.
12 x 1.50 is uncommon to start with, McMaster (what I was suggesting) has *almost* everything in the world but not this. Hex head 8.8 yes, but that's all (and as you probably know metric 8.8 < "grade 8").
Fastenal does have some 12 x 1.50, but not that long. Jeez!
Can't tell the grade on these but at least the size is right. It's a start?
