Single bolted assembly - strange behaviour

[Anonymous]

I'm seeing some strange behaviour using the Bolt Connector feature in static simulation. So I created a test piece. The steel flat should simply be rotating around the bolt, given the applied point load. Instead, it is acting as a welded/bonded joint.

The bolted connector appears to be fully fixed in place and is able to stop rotation, which appears to be a Fusion 360 bug. There is no possible way that a single bolt could resist torsion.
