A nut construction (10) is described comprising an outer tightening part (20) and an inner part (30), where the inner tightening part comprises an outer adapted surface (34), which lies against a corresponding inner opening (26) in the axial direction of the outer tightening part (20). Furthermore, a screw/bolt construction (10a) is also described comprising an outer screw/bolt part (20f) and an inner tightening part (30f), where the inner tightening part comprises an outer adapted surface which lies against a corresponding inner opening in the axial direction of the outer screw/bolt part. The invention is characterised in that the inner and outer surfaces (26, 34), respectively, of the outer tightening part (20-20f) and the inner part (30-30f), are mutually joined as a unit, with the parts (20-20f, 30-30f) being arranged to disengage from each other when the one part is subjected to a torque moment above a given limit, relative to the other part. |
