Acme thread. (Section of thread form = trapezoid.)
As opposed to paranoid hemhorroid screws which require another hole preparation H altogether.

Try a search on www.thomasregister.com (http://www.thomasregister.com) you should be able to find them - try "Metric Taps"

They also have a global search as well http://www.TGRnet.com/

Happy hunting.

JCH: I think i was thinking as you. Remembered those three sided screws, have been intending to take one to the kid at Ace Hard ware, and ask for a drill/ tap for that screw and play dumb when he made up his answer.

Naw, JCH, these guys are more creative. Needed some "split pin dowells, roll pins". I had half dozen names that I have seen them called. Went to the kids, asked for them by all the names I could think off. Got a puzzled look. Old Codger says lets look here. Box had one of the names I called them, bin had another of the names I had used, Old Codger had couple other names. Kids says "Old codger tole me they were xxxxx" Old C and I say- man you gotta understand the customer may not speak your language - you gotta learn the customers". So help me kid says he learned in HIGH SCHOOL to call things by the proper name or you don't get what you want . http://bbs.homeshopmachinist.net//smile.gif
Last time I was there the OC was still there the kid had probably gone on to a place where they have pictures and a common vocabulary (McDonalds?).

Can't beat 'em won't join 'em, never surrender!
