The module 5, designed to respond to a specific compressive force, includes a two-part deflection ring 25 consisting of upper and lower components and an outer casing 30. A fluid-filled capsule 40 is positioned between the lower component of the deflection ring and the outer casing. The module is placed under a nut, bolt head (e.g. 60, Figure 4), screw, rivet or cam-locking handle in an assembly that requires tightening to a specific force. As the required force is reached the capsule ruptures and releases the fluid. The capsule may give a visual indication that the required force has been attained. The fluid contained in the capsule may seal the thread in the assembly to prevent it being loosened due to vibration. |
