10 Groz Beckert DBX1 16X231 Ball Point Needles Description: Pack of 10 Groz-Beckert® Ball-Point Industrial Sewing Machine Needles. Needle System* : DBX1 (16X257, 16X231)Ball Point (BP) (FFG) needles are designed to alleviate making holes in knit or loosely woven materials. The cross fibers which constitute the knit or loosely woven materials are relatively far apart as compared to those in tightly woven material. When a needle with a standard "sharp" point encounters one of those fibers in penetrating the fabric, it cuts right through the fiber. This creates a hole in the fabric. The Ball Point needle pushes aside the fiber it encounters in penetration and thereby avoids making a damaging hole in the fabric. *A needle system is a group of needles made to fit specific sewing machines. All needles in a system are of the same length and shank size, but are of various diameters. Lower size numbers are narrower or thinner needles
