Abutments 16 and 17 are secured on opposite end portions of a pin 15 which protrude from an axial throughbore in a threaded stud 10. The gap between the abutments is slightly greater than the length of the unstressed stud so that relative rotation can occur. When the stud is subjected to a predetermined tension, rotation of the abutments is prevented by engagement with the ends of the stud. |
