The Enerpac Square Drive Hydraulic Torque Wrench Set, 25,547 Nm Torque, 2 1/2 in. Square Drive (RSQ19000ST) is engineered for extreme heavy-duty bolting applications where accuracy, safety, and dependability are essential. With an impressive maximum torque output of 25,547 Nm, this high-capacity hydraulic torque wrench is designed for the toughest industrial challenges, from large-scale construction projects and heavy equipment maintenance to offshore, energy, and mining operations.

Weighing 29.3 kg, the RSQ19000ST combines robust construction with ergonomic design features to deliver power and control in equal measure. The innovative housing encloses all moving parts, protecting both the tool and operator by minimising pinch points. This enclosed design ensures a safer working environment and greater reliability in harsh operating conditions.

Efficiency is built into the wrench’s operation. The 30–35° stroke maximises productivity while preventing “tool lock on,” a common issue with alternative torque wrench designs. Operators benefit from a continuous workflow, reducing downtime and ensuring bolting tasks are completed quickly and effectively. The design incorporates just three moving parts, keeping maintenance requirements low while maximising service life.

Manoeuvrability has been carefully considered, with robust handles that can be mounted on either side or the top of the wrench cassette. This flexibility enables precise positioning in restricted or awkward spaces, making the RSQ19000ST adaptable to the unique demands of field or workshop applications. Additionally, the pull-type square drive release allows operators to switch quickly between tightening and loosening, further improving workflow efficiency.

The RSQ19000ST is part of a modular system offering compatibility with interchangeable hexagon cassettes. This versatility ensures users can adapt the tool to a variety of bolting requirements without the need for multiple separate wrenches. Its power head/square drive combination works seamlessly with standard impact-quality sockets, offering a practical and durable solution for varied bolting operations.

To complement its power and flexibility, the tool is designed with accuracy in mind. It maintains constant torque output with a precision of ±3% across the full stroke, ensuring repeatable results and reducing the risk of under- or over-tightening. This reliability is critical in applications where safety and performance depend on properly tightened joints.

Ease of use is further enhanced by the reaction arm with a simple dial lock, allowing for quick repositioning or changes. This intuitive design feature contributes to faster setup and adjustment, reducing the time spent between tasks.

For optimal performance, the RSQ19000ST should be paired with Enerpac THQ700 Series hoses when used with RSL-Series torque wrenches. This ensures the integrity of the hydraulic system and maximises the tool’s service life. Following Enerpac’s “untightening rule of thumb,” users should note that loosening torque is typically 250% of tightening torque, a useful guideline when planning bolting operations.

Each RSQ….ST Torque Wrench Set, including the RSQ19000ST, comes complete with an RSQ Square Drive Head, RSL Drive Unit with short whip hoses, and a Reaction Arm, providing all the essentials needed to get started with confidence.

The Enerpac RSQ19000ST is more than just a hydraulic torque wrench—it is a high-performance tool designed for demanding industries where reliability and accuracy cannot be compromised. Its combination of sheer torque power, robust construction, safety-focused design, and ease of maintenance makes it an indispensable solution for professionals tackling the heaviest bolting applications.
