Quick Release Nut

Hydratight’s quick release nut, a compact tool with two moving parts, allows for remote activation of bolted applications. Used in more than 25 subsea projects, the nut can be quickly removed from a tightened stud bolt in less than 5 seconds per stud, dependent on the water depth, with umbilicals or remotely operated underwater vehicles, the company said. The nut uses imbedded hydraulic cylinders and incorporates a three-segment design, set into a cage, to ensure maximum security of the nut when it is in position and during application and removal. A low pressure of less than 120 bar actuates the piston rod for removal of the nut. The piston rod retracts the cage and releases the nut, immediately releasing the threads.
