The precise attention to detail and cleanliness that NASA and Grumman employed to build the Lunar Module can be seen in these packages of nuts and bolts. Each package contains one or two dozen items that are double bagged and tagged with a Bell Aerosystems (Textron) cleanliness control certification. "Opening of this package, except in an environmentally controlled clean room, will void this certification." Manufactured in Q1 1968.
