Metal Spools for Singer Sewing Machine

The metal thread collecting spools for Singer are ideal for Singer sewing machines with top loading and vertical spool system. They are compatible with most traditional models, while they are not suitable for machines with automatic loading spools that require proprietary spools. Made of durable metal, they ensure greater longevity compared to plastic spools and maintain shape and precision even with frequent use. With a height of 10.8 mm, they ensure smooth thread flow and more even tension, improving stitch quality. Perfect as spares or to keep multiple colors already wound, it is always recommended to compare the measurements with the original spool before use.
