Rigid body oscillation after drop

In the attached file, the 5 split pins continue to “oscillate” for a long time after hitting the plane… I have tried using Convex hull, but then they pass through the plane or, depending on other settings, bounce/roll off the plane.

I’d like to understand what settings are actually controlling this behavior. I’ve messed with the Friction, Damping, Rotation, etc., even the Deactivation but I can’t seem to get the right combination.
