Sewing machine 5 pack of “thin” metal spool pin. I found them to be to thin for most machines it works on some machines if you do them upside down on singer it’s too thin unless you use something to wedge in the hole.

Sewing machine 5 pack of “thin” metal spool pins. These components exhibit a diameter that may not be compatible with numerous machines; they function on select models when positioned upside down. For Singer machines, the thinness may necessitate the use of an additional object to secure them in the hole effectively.
