* Output rates and ranges can vary by: head style, blank length, mode. Lengths and outputs for the "Single Headed Blank" mode are stated in the italicized / gray cells of the table. The "S" and "SL" versions can only make single headed blanks. The ND series can also work in what is called the "asymmetric" mode, where both a short and a long screw are made at the same time, from the same wire. In the asymmetric mode, the models ND 90 and ND 91 can make a screw blank as short as 0.394 inch, along with a longer blank that is within the length range 2.36 - 5.11 inches. Within limits, the blanks can have different head styles.
