Unity Door Hinge Joint

It is perfect for doors but can also be used to model chains pendulums and so on.

Hinge joints are a type of joint that functions much like the hinge on a door allowing bones to move in one direction back and forth with limited motion along other planes.

Hinge joint a joint that groups together two rigidbodies constraining them to move like they are connected by a hinge. Useful for emulating doors and finger joints. Attaches a rigid body to another rigid body or a point in space at a shared origin and allows the rigid bodies to rotate around a specific axis from that origin. The hinge joint groups together two rigidbodies a component that allows a gameobject to be affected by simulated gravity and other forces.

Playing with the same concept more or less this week experimented some with 2d unity joints i think the issue you are having is identical to one i had yesterday the force you are applying breaks joints for some frames hence that almost spring joint effect make sure the mass and or force applied are not too heavy also maybe increase the chain parts mass makes the joints more solid too.
