Yes, that's a quill type stem. Threaded headsets use quill stems.

Here are some quill stems:

You'll need to figure out what size you need: Measure the diameter where the limit lines are. If it is 7/8 inch, then you need a "1 inch" stem. If it measures 1 inch, then you need a "1 1/8 inch stem". That probably makes no sense to you! The strange nomenclature is because the sizing here is based on the outside diameter of your fork's steerer tube. The stem goes inside the steerer and thus has to be smaller.

You'll also need to know the diameter of your handlebars (25.4mm, 26.0mm, etc.) , and how tall and how long of a stem you need.
