A latch mechanism, comprising: a hook body , the hook body having a hook body load bearing plate ; a hook mechanism , the hook mechanism having a hook and a threaded shaft connected to the hook , the threaded shaft defining a longitudinal axis (A) with respect to the hook body ; an adjustment mechanism configured to adjust an axial position of the hook with respect to the hook body ; and a bearing block , the bearing block having a block load bearing plate disposed between the adjustment mechanism and the hook body load bearing plate , the bearing block including a first boss configured for engagement with the adjustment mechanism ; characterised in that the bearing block further comprises the first boss at an axially aft location configured to engage a recess that extends in an axial direction along the longitudinal axis into a first side of an adjustment nut of the adjustment mechanism and a second boss at an axially forward location configured to engage a plate aperture that extends axially through the hook body load bearing plate of the hook body ; wherein the adjustment mechanism is locked or maintained in a position with respect to the bearing block by a lock mechanism defined by a protrusion and an aperture and that selectively prevents rotation of the adjustment nut about the longitudinal axis, wherein a sliding-fit tolerance between an inner diameter of the recess and an outer diameter of the first boss permits a set of associated components comprising the bearing block and the adjustment nut to remain tightly and precisely aligned in the axial direction along the longitudinal axis with minimal ability to move with respect to one another in a lateral direction with respect to the longitudinal axis. a hook body , the hook body having a hook body load bearing plate ; a hook mechanism , the hook mechanism having a hook and a threaded shaft connected to the hook , the threaded shaft defining a longitudinal axis (A) with respect to the hook body ; an adjustment mechanism configured to adjust an axial position of the hook with respect to the hook body ; and a bearing block , the bearing block having a block load bearing plate disposed between the adjustment mechanism and the hook body load bearing plate , the bearing block including a first boss configured for engagement with the adjustment mechanism ; characterised in that the bearing block further comprises the first boss at an axially aft location configured to engage a recess that extends in an axial direction along the longitudinal axis into a first side of an adjustment nut of the adjustment mechanism and a second boss at an axially forward location configured to engage a plate aperture that extends axially through the hook body load bearing plate of the hook body ; wherein the adjustment mechanism is locked or maintained in a position with respect to the bearing block by a lock mechanism defined by a protrusion and an aperture and that selectively prevents rotation of the adjustment nut about the longitudinal axis, wherein a sliding-fit tolerance between an inner diameter of the recess and an outer diameter of the first boss permits a set of associated components comprising the bearing block and the adjustment nut to remain tightly and precisely aligned in the axial direction along the longitudinal axis with minimal ability to move with respect to one another in a lateral direction with respect to the longitudinal axis. <EOS>
