Abstract
An apparatus having a threaded bottom assembly for interfacing to connect the bottom assembly to a second structure with threads, having a deformable element that, when sufficient force is applied via the process of threading the bottom assembly to the second structure, and at an appropriate value of axial compression or pressure, passes from a stable state, through a rapid shape transformation to a second state via a regime of reduced resistance to deformation, creating a tactile or audible indication that the apparatus has been properly installed. The deformable element may be joined to the apparatus using a circumferential ring by friction fit or spring fit, and may adhere magnetically to the second structure to facilitation installation.
