Abstract: Blind fasteners and methods of fastening are provided. A blind fastener comprises a sleeve and a mandrel. The sleeve is adapted for installation into a threaded bore in a structure. The sleeve comprises a head portion configured to receive a torque, a first sleeve end, a second sleeve end, an elongate portion extending intermediate the first sleeve end and the second sleeve end, and a cavity extending from the first sleeve end to the second sleeve end. The mandrel is at least partially disposed through the cavity of the sleeve. The mandrel comprises a first mandrel end disposed adjacent to the first sleeve end. The first mandrel end comprises an enlarged portion having a diameter greater than a diameter of the cavity. The elongate portion is configured to at least partially deform into threads of the threaded bore responsive to forcible contact between the enlarged portion and the sleeve.

Abstract: Fastening collars, multi-piece fastening systems, and methods of fastening are provided. The fastening collar comprises a first end, a second end, and an elongate portion intermediate the first end and the second end and defining a longitudinal axis of the fastening collar. The elongate portion comprises a first region adjacent the first end, a second region intermediate the first region and the second end, and a cavity. The first region comprises a first diameter and is configured to be received by a bore of a structure. The second region comprises a second diameter greater than the first diameter. The cavity extends through the elongate portion and is configured to receive at least a portion of a shank of the multi-piece fastening system. The elongate portion is configured to at least partially deform onto the shank responsive to forcible contact between the second region and an installation tool.
