The present disclosure envisions an externally controllable adjustment assembly which is carried on the bolt of a latch assembly. The externally controllable adjustment assembly is generally flush-mounted relative to the exterior surfaces of a corresponding panel and structure. A small access opening is provided to access the adjustment assembly so as to help maintain the aerodynamic design of the latch. The externally controllable adjustment assembly includes an adjuster which works with an adjuster body. An external force is applied by the adjuster to one end of the adjuster body to transfer forces to a plunger positioned at the opposite end of the adjuster body. Adjustment of the plunger helps to adjust the latching force of the latch on the structure. The present disclosure allows for controllable external adjustment as well as controllable preloading of the forces on the latch. The adjuster can be controllably preloaded by using a torque-wrench or torque measuring device to make adjustments to a desired level of force.
