Bolt intended to limit the axial travel of a moving body of a horological movement and horological movement including the same

A bolt (10) configured to limit the axial travel of a moving body (21) of a horological movement (20), said bolt (10) comprising a head (11) arranged at the end of an arbor (12) extending according to a longitudinal axis of revolution, said head (11) extending radially with respect to the arbor (12) and including a radial addendum (110) extending over a portion of a periphery of the head (11), said radial addendum (110) configured to be arranged opposite said moving body (21), and including, at the junction with the arbor (12), a bearing base (111) through which the bolt (10) is configured to rest against a structure (22) of the horological movement (20), the bearing base (111) protruding from a lower surface of the radial addendum (110) along the longitudinal axis of revolution,

• wherein the base (111) has a central overthickness (112) extending around the arbor (12) so as to allow limiting the bearing surface of said base (111) on the structure (22) of the horological movement (20), and
• wherein the central overthickness (112) has an axisymmetric cylindrical shape that protrudes from a lower surface of the base (111), the central overthickness (112) having an axis that is coincident with the longitudinal axis of revolution.
