BTW - "universal" refers to the point on the needle. That is one that works sort of ok with a wide variety of fabric. You can get them with a sharper point for heavier fabric, or with a rounder point for knits, and there are others.
Needles have Systems (what machines they fit) sizes (basically how thick the needle is ) and point types. Most modern domestic machines use the same system, but when you get into vintage or industrial, there's a lot out there!
