Classification: CPC F | IPC F

Claim 10:
11. A torque-limiting nut comprising:
a threaded component, the threaded component comprising:
a cylindrical main body having a threaded bore, an outer surface, a plurality of detents in the outer surface; and
an annular flanged portion radially extending from an end of the cylindrical main body,

a washer wherein the washer is coupled to the threaded component by a retaining device. wherein the retaining device comprises a groove in an outer diameter of the flanged portion of the threaded component, an aligned groove in the washer, and a retaining ring in the groove and the aligned groove;
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 formed in the internal bore corresponding to the plurality of detents;
a spring groove open to the recesses and the internal bore; and
an elastic member in the spring groove;

a plurality of engagement members 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
where the elastic member provides a compressive force on 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.
