These Tensioners are used for Specific Thread Size Application where the threaded piston acts as a puller too. These tensioners are specially designed for applications having space restrictions, around and the stud bolt. These tensioners are designed and supplied for specific application requirement and having the features as below:

Features of prime special bolt tensioners

  • Have a very compact dia for required load and size with nominal requirement of operational height.
  • Tool is available with standard 15mm and customised stroke as per application also
  • All parts are made from High Strength Alloy Steel for better strength and compact design.

These tensioners are designed for application where standard tensioner can not be accommodated due to space and load requirements. Working pressure may be 1500 to 2500 as per application. All parts of these tensioners are made of Special High Strength Alloy Steel for better design and safety requirement.
