ZipNuts Used to Repair Hubble Space Telescope
2/15/2000

During the Christmas season, 1999, NASA astronauts in Space Shuttle
Discovery captured the Hubble Space Telescope, repaired it and sent it back
into orbit to search deep space.

Two of the major projects, replacing a Fine Guidance Sensor (FGS) and
replacing the S-Band Single Access Transmitter (SSAT) were conducted with
ZipNut® Technology products. The FGS, which keeps the telescope accurately
pointed, was replaced with 8 Double ZipNut® Hand Tools developed with
Swales Aerospace. The Double ZipNut® tools were used by the space
walking astronauts to remove the old FGS, to install the new FGS and to
secure the old FGS into the shuttle for reentry.

The SSAT, which communicates the Hubble data back to earth, requires 8
10-32 bolts which were secured in 8 specially designed ZipNuts®.
