Abstract: A bolt (1) includes a screw (3) and an insert (2) which can be inserted in the opening (19) of a wall (5). The insert (2) includes an insert head (6) and a shaft (7) including a recess (8), the insert head (6) and the recess (8) being configured such as to, after deforming the recess (8), crimp the insert (7) on the wall (5). The screw (3) includes a break ring (14) designed for engaging with the insert head (6), directly or indirectly, with a view to deforming the recess (8) by rotating the screw and thus to obtain the crimping, and designed such that, once crimping is complete, the ring breaks and releases the screw (3) from the insert head (6), thus making it possible to clamp an accessory (4) to the wall (5). The invention also includes an assembly method using a bolt (1) according to the invention.
