Thanks for being a support group
It really is quite annoying. I have dozens of cans of random fasteners, and more boxes and bags of new. Probably 90%+ are SAE ... because ... well ... USA.
So, when I'm making a doo-dad, and need a bolt, I have every size, type, and flavor of 1/4-20 right here.
But Noooo... can't have that in my Porsche. So, I have to order that M6-30, and wait 5-days, because "Big Box Store" doesn't carry good metric stock.
(that's all just a hypothetical)
