摘要： In one aspect, cam bolts are described herein employing a dual cam surface architecture. In some embodiments, a cam bolt described herein defines a longitudinal axis and comprises a first end, a second end, at least one engagement member disposed on at least one of the first end and the second end, at least two first cam surfaces, and at least one second cam surface. The engagement member is configured to engage a torque implement to rotate the cam bolt about the longitudinal axis when torque is applied by the torque implement. The first cam surfaces are disposed about the longitudinal axis and have a first cam profile. The second cam surface is disposed about the longitudinal axis between the first cam surfaces and has a second cam profile differing from the first cam profile. At least one of the first and second cam profiles can be non-circular.
