    Abstract: A torque-limiting nut assembly, in a preferred form, includes an inner nut engaged with a shaft. A resilient torque member and a rigid torque member are positioned between the inner nut and an outer nut, with each being rotatably fixed to one of the nuts. Rotating the outer nut relative to the inner nut compresses the resilient torque member with the rigid torque member, moving the nuts along the shaft in a first axial direction until the resilient torque member is compressed out of engagement with the rigid torque member. Rotating the outer nut in the opposite direction engages the resilient and rigid torque members thereby urging the nuts in the opposite direction. The torque-limiting nut assembly provides a convenient device to apply the correct amount of application-specific torque.
