Okay. So the picture doesn’t really show what you’re getting. It’s really a threaded hole, not a super long stud sticking out.

You are getting that stick out. The threaded hole is at the end of the stud. There are multiple lengths.

Here is the long arbor- 37302 - TTS M6 Threaded Arbor: Long
Here is the shortest - 37300 - TTS M6 Threaded Arbor: Short
