Hydraulic Torque Wrench Types For Bolt Tightening Solutions


When it comes to industrial bolt tightening solutions there are many options.

Mostly commonly, your selection of choices rests between manual torquing, calibrated tightening, and bolt tensioning.

In this post, we will focus on the industrialized world’s leading option for calibrated tightening — the hydraulic torque wrench.


Two primary types of hydraulic torque wrenches

  • Hydraulic Torque Wrench Types For Bolt Tightening Solutions TTX Hydraulic Square Drive Torque Wrench - TORC - Controlled Tigthening ToolSquare Drive Torque Tools – This type of hydraulic torque wrench utilizes industrial impact sockets to apply force on fasteners for a precision mechanical fit.

A square drive torque tool is very similar to your typical hand operated torque wrench.

At AMG Bolting Solutions we offer hands-free hydraulic square drive torque tools called “TTX”.


  • Hydraulic Torque Wrench Types For Bolt Tightening Solutions TTZ Hydraulic Torque Wrench - TORC Limited Clearance Fastening - Controlled Tightening ToolLimited / Low Clearance Hydraulic Torque Wrench – Also known as, a “Low Profile controlled tightening wrench” this hydraulic torque wrench uses individual hex links to force down pressure on a nut within a tight or confined space.

The limited clearance hydraulic torque wrench carried by AMG Bolting Solutions — “TTZ” uses a power cylinder, which acts as a motor.

The power cylinder connects to hex links in various [imperial and metric] sizes to meet the requirements of various fasteners.

What bolt tightening applications are most ideal for a hydraulic torque wrench?

Both the TTX and TTZ hydraulic torque wrenches serve the needs of many diverse applications across a wide variety of commercial, recreational, and industrial working environments.

We offer world class bolt tightening solutions for:

  • amusement rides
  • mining
  • oil & gas
  • railroad tracks
  • conventional power generation
  • agricultural equipment
  • wind turbines
  • commercial foundation based
  • construction vehicles,
  • and …

many other vertical applications.

Our standard ranges of hydraulic square drive torque tools and low profile hydraulic torque wrenches are recommended for controlled tightening, and precision bolting in most of this instants.

How are hydraulic torque wrenches powered?

Hydraulic Torque Wrench Types For Bolt Tightening SolutionsAMG Bolting Solutions offers nine (9) different types of industrial pump pack units to supply power to our hydraulic torque wrenches.

We stock the most common hydraulic power pumps which are either 115v electric, 230v electric or air-powered.

Hytorc, a leading bolt tightening solutions manufacturer recently announced the release of a “lithium battery-powered pneumatic torque wrench, and its fiercest competitor [Enerpac]is believed to have one in the works.

However, these are pneumatic torque wrench tools, not hydraulic ones.

I believe since hydraulic torque wrenches require higher PSI levels, battery powered hydraulic torque tool options are a little further away.

Here are a few people who can answer your hydraulic torque wrench questions:

  • Chuck White, CWA Bolting
  • Alan Gross, AMG Bolting Solutions
  • Dan Frederick, B & F Machine Products
  • Brian Gershenoff, TORC, LLC

Do the math.

You can calculate the patterns for accurate fastener tightening every time you need to tighten multiple nuts.

Or, you can use the “Bolting Pattern & Sequence Guide” to visually see the best way.
