A hydraulic torque wrench is the tool of choice once a joint moves beyond the range of pneumatic or battery equipment. Driven by a hydraulic pump, it delivers very high torque smoothly and accurately, which is exactly what a critical bolted joint needs. Alltorc stocks hydraulic torque wrenches for everything from standard everyday bolting to the most compact BOP application.
High Torque Wrench Options
We carry two proven high torque wrench families. The Norwolf line is among the thinnest on the market, with a 40 degree stroke and a range of custom attachments to suit awkward joints. The ATW series is the durable workhorse, built to keep working in the most rugged industrial environments. Between them they cover the great majority of industrial bolting.
Flange bolting in refineries and petrochemical plant
BOP, wellhead and subsea assemblies
Wind turbine and power generation maintenance
Structural steel and heavy civil work
Mining and heavy equipment maintenance
Which Is the Right Hi Torque Wrench for You?
Start with the torque figure, then the clearance around the fastener. If the figure is high and access is reasonable, a standard hi torque wrench is the straightforward answer. If the fastener is boxed in, move to a low clearance hydraulic wrench. If you are tightening a large number of studs on one flange and need even load across all of them, a hydraulic bolt tensioner will usually be the better tool.
Pumps, Hoses and Accuracy
A hydraulic torque wrench is only as accurate as the system driving it, so the pump, hose and wrench should be specified and calibrated together. We supply matched hydraulic pumps and hoses and fittings, calibrate in house and issue certification. For lower torque work, our battery and pneumatic ranges cover up to 11,000 ft lbs.

Hydraulic Torque Wrench FAQs.
It is used to tighten and loosen large fasteners to a precise, repeatable torque, typically well beyond what a pneumatic or battery tool can manage. Common applications are flange bolting, BOP and wellhead assemblies, wind turbines, structural steel and heavy equipment.
A standard hand torque wrench relies on the operator and is limited by what a person can physically apply. A hi torque wrench is driven by a hydraulic pump, so it delivers far higher torque smoothly and consistently, without depending on operator strength or technique.
Yes. A hydraulic torque wrench needs a hydraulic power source. We supply matched pumps, hoses and fittings and will confirm the correct combination, because pairing a wrench with the wrong pump affects the torque actually delivered.
When you are tightening many studs on the same flange and need even load across all of them. A tensioner stretches the stud directly and avoids the friction losses inherent in torquing, which gives more consistent bolt load on critical joints.
At least annually, and more frequently on high cycle or safety critical work. We calibrate in house and issue certification, so tools come back quickly rather than being sent away.
