yup, they use those cam fixings, which pull everything together nice and
tight, whilst being nicely hidden.

Has anyone else noticed that they seem to have changed to plastic
for the cam part, making them a little less strong?

I'm not so sure they are weaker, I have snapped the metal ones before, but
not the plastic ones.
