    摘要： The present disclosure relates to fastening collars, multi-piece fasteners, and methods for fastening. A fastening collar comprises a first collar end, a second collar end, and an elongate portion intermediate the first collar end and the second collar end and defining a longitudinal axis of the fastening collar. The elongate portion comprises a first region adjacent the first collar end, extending a first distance along the longitudinal axis; a second region adjacent to the second collar end, extending a second distance along the longitudinal axis, and comprising a flange; and an inner collar surface defining collar cavity extending through the elongate portion from the first collar end to the second collar end. The second collar end extends away from the longitudinal axis of the elongate portion at a first angle offset from an angle perpendicular to the longitudinal axis of the elongate portion.

    摘要： Two piece tack rivets and method of forming holes for permanent fasteners. The tack rivets have a stem with a head on one end and a grooved region adjacent the other end, and a locking collar for fitting over the grooved region of the stem for deforming into the grooved region of the stem on applying a setting force between the locking collar and the stem. The head includes cutouts formed therein. The cutouts prevent the head from forming large chips or strips when drilled.
