a plate comprising an aperture defined therethrough;
a shell coupled to the plate and extending along a center axis, and comprising a sidewall, a first end, and a second end;
a compression spring disposed within the shell;
a nut comprising a first curved engagement surface, the nut disposed within the shell and moveable between a first position proximate the first end of the shell and a second position proximate the second end of the shell, wherein the compression spring is positioned between the nut and the second end of the shell to provide an axial force to the nut and bias the nut in an axial direction toward one of the first position and the second position; and
a retention washer positioned to retain the nut within the shell, the retention washer comprising a second curved engagement surface that receives the first curved engagement surface of the nut,
wherein the first curved engagement surface of the nut and the second curved engagement surface of the retention washer form a curved interface, and wherein the nut is tiltable relative to the center axis when the nut is retained within the shell by the retention washer.
