US Patent 9970468 Biased blind side temporary fasteners, systems and methods

Biased blind side fasteners and related methods for temporarily securing together at least two work pieces that each define a hole through which at least a portion of the fastener may pass. Fastener embodiments include an elongate, hollow case for substantially housing a generally cylindrical collet body and a bias element for urging the collet body into the case, and at least partially housing a central rod having a proximal end linked to a proximal portion of the case by a web element and a distal end extending from the case. Such embodiments further include a translatable plunger for temporarily overcoming the urging of the bias element and causing extension of the collet body away from the case, thereby permitting insertion of a fastener into the work pieces' holes, wherein the plunger is formed to substantially translatably pass through the web element.
