The Structural Fastener is an internal longitudinal, reversible, gear-driven interlocking screw assembly and coupling device. The Structural Fastener uses a spring-loaded, gear driven coupler shaft with a threaded stud that mates with a female threaded socket so as to form an invisible joint that is easily decoupled. The Structural Fastener can be arranged in polar or linear arrays to increase its load-bearing capabilities, its air or water tight sealing capabilities or for redundancy. The Structural Fastener makes a rigid, reliable coupling between coupled members and forms a smooth external splice that is virtually invisible. The Structural Fastener is reversible, reusable, scaleable, precisely torqueable, and can be used with O-rings or sealing gaskets to provide air or water-tight seals. The Structural Fastener provides rapid assembly or non-destructive disassembly using simple hand tools or power-driven tools thus reducing the labor required to assemble the framing for adding a Florida-style room or a greenhouse; or erecting a garage, a pool enclosure or utility building; or similar endeavors. The Structural Fastener can be scaled to meet various load-bearing requirements thus enabling manufacturers to produce shorter load-bearing members that can be assembled in a quick and efficient manner with simple tools and thus reduce shipping and labor costs.
