Self-Locking Fastener Resists Vibration, Heat

Today, engineers are successfully attacking problems from vibrational loosening to joint fatigue with a self-locking fastener called Spiralock, whose effectiveness has been validated in published test studies at leading institutions including MIT, the Goddard Space Flight Center, and British Aerospace. It has been used in extreme fastening applications, from medical implants, to the main engines of NASA’s Space Shuttle, to the Saturn Cassini orbiter and Titan Huygens probe.
