bolt (washer 1 alt)
Creates RBE2 (Nastran/OptiStruct) or KINCOUP (Abaqus) elements for the head and body.

The head elements project and connect to the nodes of the adjoining shell elements which
form the hole and also the second row of nodes which form the washer layer. The head
only connects to every other node on the washer layer. The connector location can either
be on the edge of the hole, center of the hole, midpoint in between the two holes or on
the second row of nodes which form the washer layer.
