摘要： A coiled pin (14) comprises a rectangular strip (10) of metal coiled to form a substantially cylindrical pin having leading and trailing ends with a longitudinal edge (22) on the pin exterior extending between the leading and trailing ends. The longitudinal edge (22) has a transverse slit (12) closer to the leading end than to the trailing end, thereby forming a flap (24) having a width extending between the slit and the leading end and having a free end (22') aligned with the longitudinal edge (22). When the pin (14) is fully installed and the flap (24) is immediately adjacent the exit of a hole (34), the compression of the pin (14) at the hole exit (34) tends to expand the flap (24) beyond such natural relaxation, approaching its neutral diameter, thereby providing a more pronounced mechanical stop against withdrawal.
