The Hydraulic Torque Tooling Drive Unit delivers controlled rotational force to tighten large fasteners equipped with reaction washers during assembly tasks. The unit supports accurate torque application, helping achieve consistent clamping force across fasteners. Slim geometry allows access to confined areas where standard tooling cannot operate effectively. Controlled torque delivery improves repeatability while reducing operator effort during tightening procedures. Hydraulic operation supports stable force application, improving consistency throughout installation cycles.Attributes:• Delivers controlled torque output for fastening operations.• Supports accurate tightening of large fasteners.• Enables access to fasteners located in confined spaces.Applications: The Hydraulic Torque Tooling Drive Unit operates in fastening areas around large structural joints, delivering controlled torque to install fasteners with reaction washers while maintaining consistent tightening performance.
