The Enerpac Square Drive Hydraulic Torque Wrench Set, model RSQ1500ST, is engineered for precise, controlled bolting in demanding applications. With a 3/4 inch square drive and maximum torque output of 1909 Nm at 690 bar, it’s an optimal solution for users who require reliable performance in a compact and rugged form factor.

Built for durability and low maintenance, the RSQ1500ST features a simple yet effective design with only three internal moving parts. This reduces the likelihood of mechanical failure and simplifies service requirements. It’s fully enclosed housing protects internal mechanisms while significantly reducing pinch points, enhancing both operator safety and tool longevity.

The 30–35° operating stroke allows for greater productivity with each cycle. Unlike some torque wrench designs that are prone to “tool lock-on”, the RSQ1500ST avoids this common issue, ensuring consistent performance without delays. Its pull-type square drive release makes reversing the drive for tightening or loosening fast and straightforward, even when working under pressure or in confined spaces.

Weighing just 3.3 kg, this tool remains lightweight without compromising strength. The robust reaction arm is equipped with a simple dial lock system for quick adjustments, while the optional handles can be mounted on either side or the top of the tool to enhance manoeuvrability—particularly useful in tight or awkward bolting locations.

This set includes the RSQ Square Drive Head, an RSL Drive Unit fitted with short whip hoses, and a compatible reaction arm, making it a comprehensive package for immediate deployment. The modular design is compatible with interchangeable hexagon cassettes, offering added flexibility across different applications and bolt configurations.

Torque output remains accurate to within ±3% across the full stroke, ensuring consistent fastening results and compliance with quality control standards. For users seeking enhanced system compatibility and performance integrity, Enerpac recommends pairing this tool with THQ700 Series hydraulic hoses.

As a general guideline, Enerpac advises that loosening torque should be considered approximately 2.5 times the tightening torque. This torque set is engineered with this principle in mind, delivering sufficient power to handle even stubborn or corroded fasteners effectively.

Designed for professional use in maintenance, construction, plant shutdown, and energy sector operations.
