Stud-size selection across the series
Within the Plasti-Grip 10-12 AWG family, the 1-1377173-3 uses a circular terminal — the stud size is not specified in the base listing — while the sibling 1-1377173-0 fits an M5 stud, 160296 fits a 5/16 stud, and 34855 fits a 1/4 stud; the wire gauge, insulation, and plating are shared across the series, so match the stud diameter to the mounting point.
