Is this just how it goes with expander plugs or am I missing something?
The rotation takes the path of least resistance, which all else being equal is the thread with the smaller helix angle. Loctite the expander thread and grease the preload thread.
All helpful responses, thank you. Yep always thought it was helpful to do up the top cap a little more once stem right, just to stop it loosening if anything
