Rising customer demands for superior product quality are intensifying the pressure on industrial manufacturers to uphold the highest standards in their production processes. In this context, ensuring secure tightening processes is pivotal. A stable joint can only be ensured when two components are tightened together with the correct parameters. With our latest innovation, the quality wrench STRwrench Advanced, we provide you with the capability to accurately check the quality of joints in the assembly process, ensuring reliability from the outset. 

A variety of external factors can greatly influence the integrity of the final joint. For instance, insufficient clamping force increases the risk of screw loosening. Consequently, an increasing number of customers are urging manufacturers to conduct process capability tests to guarantee flawless joints in the delivered products. Integral to such tests is the utilization of a quality wrench to verify the residual torque of the joints. This residual check enables proactive measures to be taken in response to changes in clamping force, ensuring the security of the joint.

Drawing on decades of market experience and valuable customer feedback, we are proud to present the new generation of our digital quality wrench: STRwrench Advanced. This highly flexible wrench was developed to meet the requirements of the smart factory, ensuring maximum process quality and minimizing the need for reworking.

The STRwrench Advanced reliably measures residual torque and maximum torque while offering various quality strategies for assessing and improving process quality according to industry standards. This advancement brings you closer to the overarching objective of comprehensive quality assurance and the realization of zero-defect products.

With its generously sized, robust display, the STRwrench Advanced provides all the information required for dynamic evaluation in a clear and concise way. Additionally, image-based operator guidance for joints can be accessed directly, ensuring operators are safely guided through the process. This feature proves particularly advantageous when handling multiple product variants and navigating the complexities of the production line.

The STRwrench Advanced has a patented algorithm for calculating residual torque levels. In addition, this tool features a unique modular design. Thanks to the easy to replace adapters, the so-called smartHEADs, the wrench can cover a wide torque range. In addition, the display can be rotated in 90° steps. These special features make the STRwrench Advanced extremely versatile and flexible, allowing reliable checks, even on joints that are difficult to reach.

The choice is yours: Do you prefer conducting thorough, systematic inspections? If yes, you can upload multiple inspection routes to your quality wrench. Or, would you rather perform inspections on individual joints spontaneously? With the quick programming function, spot checks of this nature are also feasible.

Thanks to its unique, robust design, the STRwrench Advanced is a reliable, durable tool for quality assurance. It effectively withstands the demanding conditions of everyday production work and is a worthwhile investment for the future.

The STRwrench Advanced is a key element in a holistic, efficient quality assurance system. With its integrated interface, the tool seamlessly connects to existing quality management software. By linking the quality wrench to the QA Supervisor software, routes, inspections, and statistical analyses can be carried out automatically. Moreover, integration with third-party QA systems is also feasible, ensuring compliance with stringent traceability and data reporting standards.
