Fine weight threads run from 60wt to 100wt. These smaller threads are ideal for intricate work such as micro quilting and fine detailed machine embroidery like freestanding designs or monograming. They can be made from cotton on the larger end to polyester on the finer end.

You may also see thread measured in Denier. For example, you may see a thread marked as Den 225. This number is saying that the weight of 9000 meters of 'x' thread is equal to 225 grams. The larger the number, the heavier/thicker the thread.
Yes, you need to use thread that is made for sewing machines, not hand stitching thread, or embroidery thread. And there are so many choices. The thread I use the most is an all-purpose thread. Your local crafting store will have a good selection to choose from.
