Needle System : 15X1SP, also sold under HAX1SP, HAX1KN, 15X1KN.

Same as Schmetz 130/705H-S Stretch Needles.

This is a special version of the 15X1 needles for stretch or elastic materials and tightly woven knits. It is made to higher standards, it has a snake's head shape due to a combination of a slightly bulged eye and a slightly reduced blade above the eye. The bulged eye opens a slightly larger space in the material and the thinner blade above the eye reduces contact between the material and the needle. This reduces needle heat-up and prevents skip stitches.

Organ® 15X1SP Needles are available in two sizes.

Size 11 (Metric Size 75)
Size 14 (Metric Size 90)

Lower size numbers are narrower or thinner needles used for lighter materials. Higher size numbers indicate a needle of thicker diameter, used for heavier materials.
These high quality Organ needles are suitable for most home sewing machines using flat shank needles including Babylock/Simplicty, Bernette, Brother, Bernina, Elna, Happylock, Janome, Juki, Mammylock, Necchi, New Home, Pfaff, Riccarlock, Simplicity, Singer, Toyota, Viking, White and More.

Needles - What the Home Sewer Needs to Know by Web of Thread

Organ Needles are Chrome Plated (Finish).
Organ no longer labels “CF” Chrome Finish or “CP” Chrome Plate because that is the “default” finish for Organ Needles.
The same is true for Groz Beckert & Schmetz as they too don’t label all of their needles “CF” either.
Rest assured that if the needles are not “PD”(titanium), “CS”, “LP”, “HP”(non-stick), they are shiney Chrome by default. Organ
