A bolt assembly has a bolt body which includes a threaded portion and a shank; a head; a ring; and a shear zone. The head is configured to transmit rotary motion to the threaded portion through the shank. The ring is disposed on the shank and has a ring thread and a tab configured to ensure continuity between the ring thread and the threaded portion. The shear zone joins the shank to the threaded portion and a complementary recess, disposed on the threaded portion, is engageable with the tab to ensure rotation locking of the ring in relation to the threaded portion.
