This is a multi-purpose stud from GM, factory part number 96228420.
Build notes: Precise fit for ease of installation.
Three numbers decide fit on a bolt: thread diameter, thread pitch and length under the head. A fourth decides survival: the property class, which sets the torque it will take.
Worth checking against the original before fitting. If you cannot read the number, we can match it from the VIN.
