Crimp ring for 18-22 AWG, #8 stud
The 485003-1: The 0.020" (0.51mm) thick steel contact carries a nickel finish; the terminal mounts free-hanging and accepts wire insulation diameters from 0.120" to 0.170" (3.05mm to 4.32mm).
Same-series ring terminals at different stud sizes
Within the same non-insulated ring terminal family, the 485003-1 (#8 stud, 0.296" outer width) sits between the 34839 (#10 stud, 0.300" width, 14-18 AWG) and the 640102-1 and 140546 (both #8 stud, 0.342" width, 14-18 AWG, brass with tin finish). The 485003-1 uses steel with nickel finish; the brass peers use tin finish — the stud size and wire gauge are the primary selection axes.
