Prym sewing machine bobbins, metal, 21.9 mm, double rotary hook

Prym metal sewing machine bobbins for double rotary hook machines

Prym sewing machine bobbins (art. no. 611352) are metal bobbins for sewing machines with a double rotary hook. The pack contains 5 bobbins, 21.9 mm in diameter and 9 mm high, so you can have several bobbins wound with different thread colours ready.

The rotary hook and the double rotary hook are regarded as robust, low-maintenance hook systems. They are found mainly in industrial sewing machines and higher-quality domestic machines. Machines with this system are made by SINGER, DÜRRKOPP, PFAFF and MEISTER, among others. According to Prym, metal bobbins last longer than plastic ones because of their robustness. On the other hand, you cannot see the thread supply through the material.

Choosing the right bobbin

The bobbin must match the hook system of your machine. If in doubt, check the instruction manual. Alternatively, measure an existing bobbin: the diameter of 21.9 mm and the height of 9 mm must match. A bobbin that does not fit will not run smoothly in the hook and may cause an uneven stitch pattern or thread problems. Bobbins for the single rotary hook or for bobbin case systems are shaped differently and do not belong in these machines.
