ABSTRACT:
A metal fastener having a well-defined yield point and improved elongation beyond the yield point and a tensile strength (force) at least as large as the specified minimum for the grade, size, and threads of said metal fastener, the metal fastener of nominal diameter D, which metal fastener comprises in combination: an externally threaded component having threads of nominal diameter D; a circular, cylindrical shank component having a diameter D.sub.S equal to or substantially equal to said nominal diameter D extending axially to one end of the threaded component; and a head component for the application of torque to the fastener extending axially to the other end of the shank component; the fastener being characterized by an axially extending hollow cavity positioned therein within the shank component, and not extending substantially into the threaded component, the maximum cross-sectional area of the hollow cavity in the shank component being greater than the minimum cross-sectional area within any part of the hollow cavity which extends into the head or threaded components.
