Yes, #43 is correct for a normal tap. (There is another kind of tap called a "roll tap" or a "thread-forming tap" that requires a different drill size.)
The best place to find this information on-line is McMaster-Carr. On their web site you can download PDFs of their catalog pages. They have a page that has tables for drill sizes and another page with the drill sizes required for various taps.

I looked on the http://www.mcmaster.com website and found what drill bits to use for each tap size.
How do I figure out what DRILL bit #43 , 36, 29 and 21 equal to ? I bought a Dewalt drill kit and they aren't numbered in the same way.
