Solistrand series stud-size matrix
Within the Solistrand ring terminal family, the 1-33220-2 uses a #3/8 stud and 0.039" (0.99mm) thickness, while the 1377172-9 uses a #1/4 stud at 0.031" (0.79mm) thickness and the 1377172-7 uses an #8 stud at the same 0.031" thickness — the wire gauge, plating, and termination style are shared across the series, so select by stud size and wire range.
