Abstract
A torque-limiting nut is provided. The torque-limiting nut has a washer, a threaded component, and a tool interface. The threaded component has a plurality of detents and the tool interface has a corresponding plurality of recesses and a spring groove. A plurality of engagement members are sized and shaped to fit within the plurality of detents and recesses. An elastic member in the spring grooves provides a compressive force to seat the pins in the corresponding detents to frictionally couple the threaded component and tool interface. When a torque required to rotate the tool interface exceeds a predetermined value, the pin moves against the spring and unseats from the detent such that the tool interface rotates without rotating the threaded component.
