The Solution: the spiralock self locking fastener
successfully survived load and fatigue testing to one-million cycles without loosening or backing out.
Besides being used in high vibration, high temperature diesel engine applications, the Spiralock locking fastener
has been validated in published test studies at leading institutions including MIT, the Goddard Space Flight Center, Lawrence Livermore National Laboratory, and British Aerospace.
Each panel is secured together using a state-of-the-art cam locking fastener
Furthermore, we have many projects under development to solve specific threaded joint applications, including a nut that will free spin onto a bolt and have prevailing torque to prevent it from coming off, a locking fastener
for soft joints (a gasket), and a tamper proof nut.
The Biomet engineers examined a snap-fit-type locking fastener
, but selected a self-locking fastener
manufactured by Spiralock Corp.
The current AD requires a one-time inspection of the coupling hinge and locking fastener
of the Gamah couplings of the fuel system tubing located in the wing dry bay to detect discrepancies, and follow on corrective actions.
For instance, Sequa used a counter bore locking fastener
arrangement to secure a several thousand pound flywheel to canning machinery.
The final choice came down to a snap-fit type locking fastener
and the Spiralock thread form.
For example, a counterbore locking fastener
arrangement secures a flywheel, weighing several thousand pounds, to canning machinery.
Stage 8 Locking Fasteners
supplies a different type of bolting solution: a system comprised of a grooved, multisided nut or bolt, a mating retainer, and a spring clip.
