Abstract: A method and a device seek to improve productivity of the installation of fasteners. Improved productivity is targeted by holding a fastener to a driving tool with mechanical components for a substantial portion of an installation sequence to prevent nuisance disengagement between fasteners and their driving tool including dropping of fasteners early in an installation cycle.
