• Durable Steel Construction – Made from premium spring steel sheet for reliable long-term performance. Each spring is manufactured with consistent tension to ensure stable bobbin braking action across all 20 pieces in the pack.
• Complete 20-Piece Value Pack – Includes 20 high-quality bobbin case springs in a convenient transparent plastic storage box. Easy to identify and organize in your workshop, keeping spare parts protected and ready for quick replacement.
• Solves Common Sewing Problems – Stops bobbin over-spin and prevents thread tangles, bird’s nests, and loose tension at seam starts. Perfect for high-speed industrial environments where machine start-stop cycles are frequent.
