A bolt 10, for use in an electrical connector, comprising a hollow cylindrical main body 11 that is open at least at a first end 13 and defines on its exterior an external thread 16. The main body 11 has an internal thread 17 at or adjacent the first end 13 in which is threadedly received a threaded contact bolt 18. The main body 11 also has received in its interior a driver member 22 that is at spaced locations drivingly engaged with the contact bolt 18 and the main body 11 and that is disconnected from the main body between the said locations. The main body includes one or more shear formations 29 and an external driver portion 31 whereby on screwing of the external thread 16 at the first end 13 of the main body into an aperture using the driver portion 31 one of the shear formations may shear such that continued screwing of the main body 11 transfers drive via the driver member 22 to the contact bolt 18 to drive it outwardly such that it protrudes from the end of threaded section 17 of the first open end 13. |
