Flown main engine gimbal bolt from Space Shuttle Discovery Engine #2, measuring 4.75″ long with the diameter of the head measuring 1.25″. This was one of eight bolts from Engine #2 of shuttle Discovery (OV-103) which were bolted to Discovery’s main engine gimbal bearing assembly located between the main engine and the orbiter. Upon inspection after landing, this bolt was removed because of flight hardware damage due to its expired torque/time cycle limit. In fine condition, with lubricant residue to the threads. Accompanied by a color copy of the parts removal tag, task maintenance form, and supporting paperwork and documentation. The tag identifies the bolt as “Part No. MD111-4035-0001” and that it was “Removed OV-103 Eng #2, 2/8/99.”
