Abstract
The probability of thread damage during the joining of carbon or graphite electrodes having tapered threaded projections or sockets is reduced by an improved thread configuration wherein the thread crest angle is less than the taper angle of the threaded projection or socket. In the preferred embodiment the thread crest is essentially parallel to the electrode axis.
