Method and apparatus for fastening steel framing using helical features

摘要

A pin with threads that extend along a portion of a stem of the pin interact with framing members as the pin is driven through the framing members. The interaction of the threads with the framing members cause the pin to rotate as the threads pass through the framing members and fastens the framing members together. A pin with curved wings that extend along a portion of a stem of the pin interact with framing members as the pin is driven through the framing members. The interaction of the wings with the framing members cause the pin to rotate as the wings pass through the framing members and fastens the framing members together.
