ZipNuts® for NASA Space Exploration



















ZipNut® Technology was first used by NASA in 1989 when a ZipNut®
Tool was developed for Shuttle Flight STS-29. Based on that success, a
ZipNut® was then selected to be a key mechanical element for the
robotic assembly of the International Space Station. In 1992 NASA
adopted the technology for the Hubble Space Telescope Repair. This
history and the current widespread space application was formally
recognized by NASA in its Spinoff 1998 publication.

ZipNut® is a "Recommended Technique for Effective Maintainability" in
"Selection of Robotically Compatible Fasteners and Handling
Mechanisms" (NTM 4628) in NASA's official Policy for Safety and
Mission Success (NPD 8700.1).

*Swales Aerospace has joined ATK, (www.atk.com) an advanced weapon and
space systems company. Swales has been working with ZipNut® products
since 1993 when Swales engineers working on the Hubble Space Telescope
Repair Mission for Goddard Space Flight Center led the development of the
Double ZipNut® tool which was used to repair the deficient Hubble camera.
Swales has guided ZipNut® use on three subsequent repair missions and
ZipNuts® have been delivered for the next Hubble repair mission.

Additional Information: ZipNut Technology, LLC, is experienced in
designing and supplying parts and special design tools for aerospace
programs. ZipNuts® are especially adaptable for robotic use in space
and sub-sea conditions. They can be an excellent holding device as well
