The Groz Beckert MR7 Size 200 (NM 200 / Size 25) is the strongest in the MR needle range, purpose-built for heavy-duty, multidirectional industrial sewing applications. Whether you're stitching multiple layers of coated materials, thick leather, or dense woven fabrics, these needles deliver exceptional performance and reliability.

Featuring Groz Beckert’s trusted MR geometry, the MR7 is designed with a robust blade that resists deflection under lateral forces, ensuring precise needle movement even during curved or reverse stitching. The Regular Round Point (R) and long scarf design improve loop pick-up, reduce skipped stitches, and minimise thread damage, especially when changing sewing directions.

• Extra-Heavy-Duty MR7 Needle Design – Ideal for high-tension, multidirectional stitching on the toughest materials.

• Regular Round Point (R) – Slightly sharp tip offers clean penetration with minimal material damage.
