These needles are made for sewing hard, thick or heavy materials. They will sew through multiple ply applications like quilting, jeans, appliqué or heavy embroidery. It is actually an industrial needle with a flat shank. If you are bending or breaking regular needles (15x1’s) this needle could solve your problem.

They are available in either sharp or ball point with a hard chrome or titanium finish.
