Ring terminal for 10-12 AWG on an #8 stud
The 34853 is the #8-stud member of TE's Plasti-Grip ring terminal line, accepting 10-12 AWG wire with a serrated crimp barrel that grips the conductor through the insulation. Yellow PVC insulation covers the crimp barrel over a 0.150" to 0.250" insulation diameter range; the tin-plated copper contact is 0.040" thick at the ring.
