1. A fastener comprising:
a housing including a housing opening;
a collet body at least partially enclosed within the housing, the collet body including:
a crown having a crown opening with a threaded section; and
a leg extending from the crown and including a foot;
a screw with a head positioned in the housing opening, an upper threaded section designed to threadingly engage with the threaded section of the collet body, and a lower unthreaded section;
wherein the housing opening and the crown include a set of splined protrusions and a set of splined recesses mated with one another; and
wherein the sets of splined protrusions and recesses include ramps and are designed to permit the collet body and the screw to transition into a free-spin configuration where the screw and the collet body freely rotate such that the collet body does not axially translate in relation to the housing; and
a spring designed to exert a return force on the collet body when the fastener is in the free-spin configuration.
