The Enerpac Square Drive Hydraulic Torque Wrench Set, 7191 Nm Torque, 1 1/2 in. Square Drive (SKU: RSQ5000ST), is built for precision-controlled bolting in heavy-duty industrial settings. This set combines high torque output with advanced ergonomic and safety-focused engineering, making it an essential solution for high-strength bolting applications where repeatability and reliability are critical.

With a maximum torque capacity of 7191 Nm and operating pressure up to 690 bar, the RSQ5000ST is designed to deliver consistent results in demanding environments. The square drive interface (1 1/2 in.) is compatible with standard impact-quality sockets, and the set includes everything needed for operation—RSQ square drive head, RSL drive unit, short whip hoses, and a reaction arm—making this a fully integrated torque solution.

Enerpac’s innovative approach to design ensures that all moving parts are completely enclosed, which significantly reduces pinch points and enhances operator safety. The tool’s 30–35° operating stroke contributes to improved productivity by reducing cycle times and avoiding the common “tool lock-on” issue experienced with some competing models.

A major advantage of this torque wrench set lies in its mechanical simplicity. With just three moving parts, maintenance is minimal and tool durability is enhanced, even in challenging job site conditions. Robust handles can be mounted on both sides and the top of the cassette, providing superior control and manoeuvrability in tight or awkward spaces.

Reversing between tightening and loosening is fast and intuitive, thanks to a pull-type square drive release mechanism. This supports efficient switching without disassembly, making the tool adaptable for a wide range of bolting tasks. The reaction arm further streamlines operations with a simple dial lock, allowing for quick and secure repositioning when changing bolt locations.

Torque accuracy is maintained to within ±3% across the full stroke, supporting reliable fastening performance that meets the demands of critical bolting applications. This is especially important when adherence to strict engineering tolerances or load specifications is required. For safe and reliable untightening, Enerpac recommends applying the rule of thumb: loosening torque should be approximately 250% of tightening torque.

To ensure full hydraulic compatibility and safety, the RSQ5000ST should be used with Enerpac’s THQ700 Series hoses. These hoses are engineered to maintain system integrity and withstand the pressures and flow rates required by RSL-series torque wrenches.

For operations requiring interchangeable tooling, the RSQ Series also offers compatibility with hexagon cassettes, allowing users to switch between square drive and hex drive configurations with minimal downtime.

Engineered for heavy-duty performance, easy handling, and reduced maintenance, the Enerpac RSQ5000ST set is a high-capacity hydraulic torque solution that combines intelligent design with industrial-grade durability.
