The Pfaff® Denim Twin Needle is built for bold, reinforced topstitching on heavy-duty fabrics like denim, canvas, and twill. With two size 100/16 needles spaced 4.0mm apart on a single shank, this twin needle is ideal for creating strong, parallel seams that add both durability and decorative flair. Whether you're sewing jeans, hemming thick garments, or adding rugged accents, it delivers clean, even stitches through multiple layers. Engineered with a reinforced shaft and sharp point, the Pfaff® Denim Twin Needle easily penetrates dense fabrics while helping prevent skipped stitches and reducing the risk of needle breakage. Each pack includes one premium-quality 4.0mm twin needle in size 100/16—perfect for tough sewing jobs that demand strength and precision. For optimal performance, replace your needle every 6 to 8 hours of sewing or whenever you switch fabric types.
