Hydraulic Nuts

Check up to five results to perform an action.


  • Trouble-free, No-Leak, Lo-Friction Seals.
  • Overstroke Indicator.
  • Extra-Long Working Stroke.
  • Compact and Lightweight Design.
  • Simple to Operate and Maintain.
  • Total Quality Assurance.
  • Dependable Operation.
  • Collar, Shim, or Hydraulic Bolt Styles.
Compact, Easy and Accurate!

The Hydraulic Nut replaces the nut normally used and stays with the stud. This is the most compact system and does not require additional stud length. The operator simply screws the nut down tight and connects the hydraulic hoses. After reaching pressure, he either screws down a collar (style illustrated) or inserts shims designed for the application.
  • A minimum of one thread diameter of thread engagement is recommended.
  • Stud Load is directly proportional to the pressure applied.
  • For top ports allow 9 inches (23 cm) above Tool for Hose and Fitting clearance.
  • Side ports are available on Models NG and larger.
