The reason I say don't through harden it is you'll get brittle threads, and there is a risk of marring them by oxidisation while heating. If you do harden, then as Tom says temper afterwards, but pack the threaded hole with something to keep the oxygen at bay, fire clay or whiting.
Thanks very much for the valuable tip. So much to learn!
