It rivets the head. Having grown up riveting knives on sickle bars and
riveting other things, I rivet the new style with a small ball peen
hammer. I am old enough that i spent Jr. High shop peening aluminum,
thereby having a first hand knowledge of how the hammer gets its name. I
guess there were people who were not careful enough to get the clip snapped
in properly, so the master link has been officially banned. I did them for
years and never had one come apart, but i always checked my work to be sure
the clip was clipped correctly, since it is critical.
Since you also worked on OM 621 engines, I am sure you can rivet the link
without the special tool.

Does the special tool "rivet" or "brad" the chains patch link together?
The only one I've done; on a '67 200D; had a bicycle chain type patch link
that snapped together without using a special tool.
