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 four subsequent repair missions including the
May, 2009 mission.

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
ZipNut® history and the current widespread space application was
formally recognized by NASA in its Spinoff 1998 publication.
