Roman cast copper alloy lock pin. The lock pin has a circular head which is slightly concave. There is a central raised pyramidal boss with a circular cross section and a depressed circle at its apex.

The shank has a sub-circular cross section where it joins the headplate, the cross section changes to rectangular. The shaft is 23.53mm long, with a diameter of 6.31, and a width of 5.57mm by 3.63mm at the terminal. There is a cast, sub-rectangular opening at the end of the shaft, measuring 6.05mm by 1.52mm.
