Claim 13:
14. A torque-limiting nut comprising:
a threaded component, the threaded component comprising:
a cylindrical main body having a threaded bore and an outer surface; and
an annular flanged portion radially extending from an end of the cylindrical main body, the annular flanged portion having a tool interface surface comprising a plurality of spaced detents,

a tool interface, separate from the threaded component, having an internal bore sized to receive the cylindrical main body of the threaded component, the tool interface comprising a plurality of recesses corresponding to the plurality of spaced detents;
a plurality of engagement members wherein each of the plurality of engagement members comprises a ball wherein the plurality of engagement members are configured to reside, in part, in the plurality of detents and, in part, in the plurality of recesses; and
a plurality of compression members wherein each of the plurality of compression members comprises a spring in the plurality of recesses, wherein each of the plurality of compression members provides a compressive force on each of the plurality of engagement members such that rotation of the tool interface causes the threaded component to rotate until a rotational torque applied to the tool interface exceeds a predefined torque-limit.
