Claim 0:
1. A plunger disposed in a bore in a shaft of a self-locking pin, the plunger comprising:
a single continuous piece of wire having first and second ends;
the first end of said wire being helically wound three or more windings to form a plunger section, said plunger section comprising a plurality of substantially parallel helical coils proximate to one another and defining a first coil axis;
the second end of said wire being helically wound to form a base section, said base section comprising a helical coil contiguous with an end coil of said plunger section and defining a second coil axis, said second coil axis being perpendicular to said first coil axis; and
said helical wire windings of said plunger section being substantially orthogonal to said single wire winding of said base section, and a diameter of said winding of said base section being at least a width of said windings of said plunger section in a cross-sectional plane perpendicular to said first coil axis;
wherein the shaft of the self-locking pin has a longitudinal axis and the bore has a bore axis, the bore axis being perpendicular to the longitudinal axis; and
wherein said base section of the plunger is coaxially disposed within the bore in the shaft of the self-locking pin and wherein a biasing force is applied to said base section, coaxial with said second coil axis of said base section, such to bias said plunger section outwardly from the shaft of the pin.
