Safe, faster and accurate bolt tensioning is achievable when using Technofast Industries’ A3 Spring Return HydraJacs.

Longer bolt life due to the elimination of galling and thread pick up as a result of frictional force applied to the thread. When using Technofast Tensioners the nut is never turned while under load

There is no requirement for a reaction point as the tensioner reacts on the spot face adjacent to the nut

Tensioners are generally lighter then the combined weight of a torque wrench and impact socket or cassette

Technofast A3 modular tensioners are simple in construction and use requiring only minimal operator training and require little physical effort to use

By the removal of the effects of friction from the calculation, a more accurate and consistent bolt load is obtained which is highly beneficial when specifying gaskets loads, etc.


The A3 HydraJac kit is equipped with everything you will need to service your equipment. It also includes pumps, hoses and accessories for easy application of several tensioning tools.

The A3 HydraJac kit may include:

  • A3S Spring Return HydraJac with adaptor kit
  • Air hydraulic pump, air/hydraulic unit pump combination or hand pump
  • Hoses and fittings
  • Porting blocks
  • Tool box

In addition to being cost effective, the A3 HydraJac kits are quick and easy to use with minimal training or experience, eliminating several WH&S risk factors in lifting and pinch point crush injuries.

For several industries and critical bolting applications you can have Technofast Industries tailor a tensioning tool kit from you, from 1—100 load cells and as many adaptor kits in a wide variety of thread sizes and types both metric or imperial or a combination of both.
