Holey kow, wizzed, you ... are ... de ... MAN!!!!!
LOL, I actually rec’d notice of your extraordinary post while in the “Fasteners” aisle in a local Home Depot so, now, I can assert: Home Depot is NOT a “real hardware store.” (Big box yes; stainless let alone metric hardware, meh.)
That’s okay, you have given me the motivation to hunt these fasteners DOWN!
If you EVER get over near Hickory, NC, just give me some advance notice cuz, your beverages of choice (and boolits if you needs ‘em) are ON ME!!!!!
