A threaded pin (10) for connecting carbon electrodes is presented. The pin includes a body (12) having a central axis running along its length, two end portions (16 and 17), a midpoint (18) lying between the two end portions and threads (20a, 220b, 20c, etc.) extending from the body. The threads each have at least two side walls (22 and 24), wherein the side wall facing the midpoint of the body of at least a plurality of the threads has an angle of between about 75 DEG and about 90 DEG with respect to the central axis of the body. |
