Two flown Gimbal nuts, flown on Discovery mission STS-91, the final mission to the Mir space station. Both bolts are 1.25” in diameter at their base. Bolts were torqued four times and were then changed out after the mission. Accompanied by a photocopied Post Operation Instructions form, dated September 28, 1998, which states “If any Gimbal bolt/nut has been torqued four times, all eight nuts and bolts for that engine position must be scrapped.” Form identifies that four nut and bolt cycles were changed out. In fine condition.
