The12-thread series (12-UN) is a uniform pitch series for large diameters requiring threads of medium-fine pitch. Although originally intended for boiler practice, it is now used as a continuation of the Fine-Thread Series for diameters larger than 11⁄2 inches. 5/8" - 1 7/16" 1 9/16" - 2 1/8" 2 1/4"- 3 1/8" 3 1/4" - 6".
