The invention relates to a break-off bolt (1) for securing a conductor (52) within a connector (38), the break-off bolt (1) having a first thread section (2) and a second thread section (4), the first and the second thread section (2, 4) comprising the same external thread (6) with a minor diameter (8), the break-off bolt (1) further comprising a torque-limiting section (10) arranged between the first and second thread section (2, 4), wherein, in the torque-limiting section (10), the break-off bolt (1) has at least one of no thread with an outer diameter (12) larger than the minor diameter (8) of the external thread (6) and an external thread (26) having a minor diameter (28) larger than the minor diameter (8) of the first and second thread section's (2, 4) external thread (6). Therefore, the break-off bolt (1) can easily be installed with a predetermined torque without the necessity of a torquewrench.
