Only recommended for long arm quilters and AQSD-16 machines

Anatomy: Unlike a standard sewing needle, long arm needles have a round shank and specially made for use with long arms machines that shift and change stitch direction. Groz-Beckert needles have superior strength and a flexible shaft with a deep scarf to help prevent skipped stitches, puckering and thread breakage, especially at high speeds.

Recommended Uses: With a rounded shank and a deep scarf, Groz-Beckert size #14-18 needles have superior strength and flexibility. Only recommend for long arm and sit down quilting machines.
