Solistrand ring terminal for 10-12 AWG
The 1-320765-1 is the 10-12 AWG, #7/8 stud member of TE's Solistrand ring terminal line, a circular terminal with a brazed seam and serrated termination. The 0.039" (0.99mm) thick tin-plated copper body accepts 10-12 AWG wire via crimp termination and is rated for free-hanging in-line mounting.
Stud size and wire gauge ladder
Within the Solistrand series, the 1-320765-1's #7/8 stud and 10-12 AWG wire range sit above the 1377172-7 (8 stud, 14-16 AWG) and the 133521-1 (8 stud, 18-22 AWG) — the brazed seam, serrated termination, and tin-plated copper construction are shared across the series, so match the stud size and wire gauge to the cable and panel hole.
