re: Source for small black oxide wood screws?

McFeely’s doesn’t seem to sell #2s, and their “screw finder” doesn’t work on my iPad (or perhaps due to my ad-blocker). McMaster doesn’t sell #2s in black oxide. OSH returns outlet plates when I search for “wood screws”. I came up blank on Amazon and eBay as well, which is why I asked here.

Applying brass-black to the hundreds of screws I’ll use in a couple years is a pain (the hinges I buy take 6 screws per hinge, and #4 screws won’t fit, so I need #2 or #3s), and I get maybe 30% yield after drying them and having the finish flake off over half.

I also tried Wild West Hardware, who specialize in black oxide fasteners, but don’t sell anything smaller than #6s, ditto for Blacksmith's Depot, and BlackSmith Supply.

I’ll guess I’ll send an email to Fastenere. They’re my go-to for screws generally, but don’t stock black oxide smaller than #4s.
