The Enerpac Square Drive Hydraulic Torque Wrench Set, 10,659 Nm Torque, 1 1/2 in. Square Drive (SKU: RSQ8000ST), delivers reliable performance and precision for heavy-duty bolting applications. Combining exceptional torque output with a compact and robust design, this tool set is engineered to perform consistently in demanding industrial environments.

With a maximum torque capacity of 10,659 Nm and a minimum torque of 1,066 Nm, the RSQ8000ST offers a wide operating range suitable for a variety of high-load tasks. It’s 1 1/2 inch square drive ensures compatibility with standard impact-grade sockets, providing flexibility across numerous bolting applications.

The tool’s innovative design fully encloses all moving parts, significantly reducing the risk of pinch points during operation. This feature enhances operator safety without compromising access or efficiency. A 30–35° operating stroke improves productivity by reducing cycle times and avoiding common issues like tool lock-on, which can disrupt workflow in alternative wrench designs.

Built with only three moving parts, the RSQ8000ST is engineered for minimal maintenance and long-term reliability. Its straightforward internal construction reduces the likelihood of mechanical failures and simplifies servicing.

Robust, removable handles can be mounted on either side or on top of the cassette, improving manoeuvrability in tight or awkward spaces. A pull-type square drive release allows for quick reversal between tightening and loosening functions, streamlining operation. The square drive can also be paired with interchangeable hexagon cassettes for even greater application versatility.

The integrated reaction arm features a simple dial lock mechanism, allowing rapid and secure adjustment without the need for additional tools. This thoughtful design detail helps to reduce setup time and keep operations running efficiently.

Torque output is maintained consistently throughout each stroke, with an accuracy of ±3%, making the RSQ8000ST a reliable choice where precise torque control is critical. This performance standard ensures repeatability and compliance in controlled bolting applications.

When selecting a hydraulic torque wrench, Enerpac recommends following the general rule of thumb for untightening: the loosening torque should be approximately 2.5 times the required tightening torque. This set is designed with that ratio in mind, offering the necessary output for both fastening and removal tasks.

The RSQ8000ST set includes an RSQ square drive head, an RSL drive unit with short whip hoses, and a reaction arm. For optimal system integrity, use the Enerpac THQ700 Series hoses in conjunction with the RSL-Series drive unit.
