The spike on the front of each plug is fixed, only the back flare has threading. Each plug has a 1/4" wearable area.

These things look awesome! The only minuses are they aren't the most comfortable to sleep in, so I don't recommend that, and the back to these that screw on are kind of difficult and loose. So as an easy fix I just used some good ole fashioned o-rings that I got with my order! But they're light and super cool!
