12-16 AWG ring terminal for #8 stud
The 61624-1: The brass contact is 0.025" (0.64mm) thick with inner teeth and serrated termination for grip on stranded wire; the insulation diameter range is 0.130" to 0.170" (3.30mm to 4.32mm).
Crimp termination, free-hanging mount
Termination is by crimp only, with the terminal mounted free-hanging (in-line) — no insulation support barrel, so the crimp must be applied to the bare conductor within the specified wire range.
Peer terminals in the same stud size
The 61624-1 (0.025" thick, 12-16 AWG) is thicker than the 140546 (0.024" thick, 14-18 AWG) and the 640102-1 (0.030" thick, 14-18 AWG) — all three are #8 stud, non-insulated, free-hanging brass ring terminals, so the wire gauge and thickness are the selection axes.
