Behind the Scenes
As revealed on crates seen by the player in the Atlantic Express, Trap Rivets are produced by Sinclair Solutions. They are 60mm, designed for Protectors (AKA Big Daddies), and are "Sensor-Released." The crate texture can be seen in the gallery above.
In the early development of BioShock 2, "Heavy Rivets" were originally supposed to be called "Magnum Rivets", as shown in the BioShock 2 E3 2009 Demo.
