ABSTRACT:
A needle for use as part of a fastener dispensing tool adapted for dispensing plastic fasteners of the type typically used to attach tags to products for marking and identification. In one embodiment, the needle is made from a single sheet of metal by a stamping and/or rolling technique, and comprises an elongated, generally cylindrical, hollow, slotted member having a stem portion and a base portion. The stem portion terminates at its front end in a relatively sharp tip. The base portion, a portion of which is sized and shaped for insertion in an opening in the nose of the tool, includes a pair of upwardly extending, spring tabs bent outwardly away from each other. A first portion of one of the tabs is sized and shaped to releasably engage a recessed area formed in the nose of the tool to prevent unintended removal of the base portion from the opening and to limit rearward insertion of the base portion into the opening. A second portion of the same tab is sized and shaped to engage another wall of the nose to prevent upward movement of the base portion in the opening. The other tab, serves as a registration member to align the base portion in its desired longitudinal, vertical and angular orientations.
