System 16x231 is generally used in single needle lockstitch industrial sewing machines. It is also known as 16x257, 1738, 2270, DBx1, and DBx257; and in sizes 9 through 18 only as 16x95, 287WH, 1738A, and 1738AK.
Please note that 16x231 refers to the system, or type of needle; size (diameter) is denoted by the suffix. For example, 16x231-9 is the smallest, or thinnest size we offer in this brand; 16x231-23 is the largest, or thickest size.
The eye of the needle increases with the thickness to allow for sewing heavier threads. Needles listed here are standard sharp point only.
Sold in packs of 10, 50 and 100.
