Abstract: Self-forming thread blind fasteners and methods for fastening are provided. The self-forming thread blind fastener comprises a sleeve and a pin. The sleeve comprises a first sleeve end, a second sleeve end, an elongate portion, and an inner wall defining a bore. The pin is configured to be at least partially received by the bore. The pin comprises a first pin end, a second pin end, a pin head portion, an at least partially threaded portion, a shank intermediate, and a driving portion. The at least partially threaded portion is configured to form threads on at least a portion of the inner wall of the sleeve. The driving portion is configured to receive a torque to rotate the pin within the sleeve and thereby axially compress and deform the sleeve and form the threads on the at least a portion of the inner wall of the sleeve.
