GROZ BECKERT 16 X 257

System 16×231 is generally used in single needle lockstitch industrial sewing machines. It is also known as 16×257, 1738, 2270, DBx1, and DBx257

Please note that 16×231 refers to the system, or type of needle; size (diameter) is denoted by the suffix. For example, 16×231-9 is the smallest, or thinnest size we offer in this brand; 16×231-20 is the largest, or thickest size. The eye of the needle increases with the thickness to allow for sewing heavier threads.
