Abstract
A single side temporary fastener (SSTF) capable of maintaining a clamping force in a material stack subject to material creep or adjunct extrusion during clamp up processes is disclosed. The SSTF comprise a rotationally constrained but freely translatable collet body that is disposed within an auxiliary structure such as a fastener housing. A fastener comprises the aforementioned collet body, which at least partially translates within the aforementioned auxiliary structure, and further comprises a threaded screw for rotationally engaging with the collet body, which by way of an antirotation means associated therewith and with the auxiliary structure, is rotationally constrained but is free to axially translate. Constant clamping pressures are made possible in such embodiments by the inclusion of at least one biasing element between compression force transmitting elements and/or assemblies of the fasteners.
