I have to plead naivety in not knowing about the #12 screws. They are listed in both the Machinery's Handbook and the Mark's Mechanical Engineers' Handbook. The latter I used exclusively until someone mentioned the Machinery's. However, naivety is no excuse. A couple of the screw "slide" cards I have, Holochrome and Unbrako, don't list the #12s so it must be their fault.
Thanks again for the input.
