An M8 thread is made to the center hole of the profile with a Threading tap M8. The Fastlock 45 screw is first screwed all the way to the bottom, and then opened 1 whole turn. After this, the Fastlock is slid into the groove of the other profile and tightened with the set screw in the desired position. A short (to use with an End Cap) and stainless steel -versions also available.
