Heavy duty sewing needles are specially crafted to sew through multiple layers of fabric, heavy materials like denim, upholstery, leather, and canvas. The most notable difference between standard needles and heavy duty needles lies in their construction. Heavy duty needles have a thicker shaft and a larger eye, which allows them to accommodate thicker threads and withstand greater tension without bending or breaking. They come in various sizes, with the most commonly used sizes ranging from 90/14 to 110/18, indicating their increased strength and capacity for thicker materials.
