10 plastic bobbins for domestic/houehold sewing machines.

3/4 inches (20.5 mm) wide & 7/16 inches (11.5 mm) thick 1/4 inches (6.4 mm) hole diameter

These are the most commonly used bobbins for most types of Home Sewing Machines. These bobbins have slots (for bobbin winder) and have one hole in each side. These machines generally have a “Shuttle Hook.”

What is a Shuttle Hook?

The Bobbin fits into the machine’s Bobbin Case. In turn, the Bobbin Case fits into your machine’s Hook. The Hook is either a ROTARY or a SHUTTLE Hook. To determine which Hook your machine possesses, turn the machine in the normal direction slowly and observe the Hook. It if rotates continuously, then it is a ROTARY Hook. If it travels “back and forth,” then it is a SHUTTLE Hook.
