ABSTRACT:
An apparatus used in steam turbines for locking a nozzle block and nozzle chamber together. At least one modified cap screw is engaged with the nozzle block and nozzle chamber and tightened to a required torque. A plate is affixed to either two or more modified cap screws or to both a modified cap screw and the surrounding base metal of the nozzle block or nozzle chamber with one rivet passing through the plate into the modified cap screw and a second rivet passing through the plate into the nozzle block, nozzle chamber, or other modified cap screw. The rivets and attaching plate restrain relative motion between the cap screw and the surrounding base metal of the nozzle block or nozzle chamber thus preventing the modified cap screw from loosening.
