Abstract
A vibration-tolerant torque limiting fastening lug whereupon tightening of the set-screw produces a parasitic torque at the thread plane defining the set-screw/housing interface. The resultant parasitic torque acts in opposite direction to the installation torque such that the actual torque below the thread plane is less than the installation torque. As a result, the tensile force experienced by the set-screw and which acts against the housing of the lug is reduced.
