try google "Micro Self Tapping Brass"
I use a Grex micro-pinner and stainless pins for a number of things. Works best in hardwoods, but in any case, is meant to be supplemental to glue. I doubt "self-tapping brass" would self-tap anything harder than butter on a warm day. In all such cases, pre-drilling a correct diameter pilot hole is mandatory. With most hardwoods, you might even break off miniature drills bits if they aren't high-quality cobalt steel. That isn't a random prediction, by the way. One more reason to shop McMaster or some other serious supplier. I even keep on hand a high quality high-RPM air drill to get small bits into hardwood fast fast before the alloy overheats. Resinous tropical hardwoods can break bits like crazy if they aren't heat-resistant cobalt.
Much the same, I like to secure bits of hardwood with micro spectacle screws after creating a hole win a cobalt pin drill, these type of fasteners are very inexpensive on the bay. I think they are better than brass self tappers as they take a good grip in a hardwood hole of the right diameter. Sometimes a little glue on the thread if they are permanent.
Suggest using a type A thread stainless steel sheet metal screw. These work very good in wood.

Go to a good hobby store that has a electric train section.
Walthers is also a good source and have a great catalog of small hardware and tools. Walthers.com
Hope this helps.
