    Oversized tap for internal threads mating with HDG bolt

    Does anyone know of a tool manufacturer that will make special taps? I need an oversized tap that will meet the allowable dimensions in ASTM A563 for overtapping nut thread to permit assembly on a hot dipped galvanized bolt. I am having no luck getting anyone I know of to make this.
