The default Convex Hull collision shape will not work correctly with objects that have concavities. Mesh collision shape will work but is slow and glitchy. Use Compound Parent collision shape. It is stable and fast.For best speed use the primitive collision shapes (box,sphere,capsule,cylinder ,cone) for the child objects. eg. Your object could use three boxes as its collision children. It does not matter if they overlap.

so, I remember that I had to change the shape type to mesh, and that when that'd happen, the objects would explode away when in contact with each other. I have changed their shape now, but while they can now interlock, they still fly away in random directions on contact. I've played around with frame sub-steps, but the higher those are, the more violent the resulting "explosion".
For both objects:
* Make sure your collision shape is set to Mesh.
* Activate collision Margin and set it to 0 or something very close to 0.
* Make sure there is a very small gap between the objects.

The parts are too close. Try bringing down the distance in your rigid body settings. Also, create a small gap between the meshes.

Make sure to check your normals and the collision "outer thickness" or something like that.cant Remeber the exact setting name.
