A fastener comprises a pin and a bushing having a hollow shank that is inserted into holes in a plurality of members being attached. A pin shank is inserted into the bushing shank to effect a widened-diameter coupling condition in which the diameter of the bushing shank is widened, and the members being attached are coupled between the diameter-widened bushing shank and a bushing flange. On the bushing shank are pawls for maintaining a non-widened-diameter coupling condition in which the pin and the bushing are coupled with the pin shank partially inserted into the bushing shank, and the diameter of the bushing shank is not widened. On the pin shank there is a groove for engaging the pawls, which normally extend out beyond the diameter of the attachment holes, but can bend inward. The groove has a depth that will accept the pawls when they are bent inward.
