Correct C3P0 neck bolt/socket system?

[kurtyboy]

These fasteners are on the neck bolts and also the torso bolts. Looks like some kind of twist lock system.


Anyone know what they are called and what the sockets on the neck are?

Those are Dzus quarter turn fasteners. They used them on ESB onwards. For Anh they used threaded bolts that inserted into the neck collar.

Dzus fasteners are used on race cars and such, to quickly remove the body panels.

Hope that helps!

Thanks for clearing that up!

Do you have any reference showing the ANH neck collar sockets?
