At Ansomat, no inaccessibility issue is too complex - we are known for delivering solutions that enhance both reach and efficiency on the production floor.
A Toolkit for Any fastening project
Low torque reaction tools engineered for delicate and precision assembly feature compact housings, lightweight materials, and finely tuned clutch systems that ensure minimal kickback and maximum operator comfort. Their ergonomic grip, low noise output, and smooth, vibration-controlled operation make them ideal for electronics, small mechanical assemblies, and workstations where accuracy is critical.
Many models offer adjustable torque settings, high repeatability, and compatibility with suspension systems to further reduce strain during continuous use. Built for reliability and precision, these tools deliver consistent fastening quality, enhanced safety, and improved productivity in environments that demand controlled, low-reaction performance.
DC direct-drive tools utilize a high-efficiency brushless motor to deliver smooth, continuous torque directly to the fastener, ensuring exceptional accuracy and repeatability in tightening applications. Their direct mechanical connection allows for precise torque and angle control, making them ideal for tasks that require consistent, traceable results.
These tools often integrate intelligent controllers that record fastening data, monitor performance in real time, and support process optimization across production lines. With low maintenance needs, excellent reliability, and compatibility with automated systems, DC direct-drive tools provide a clean, efficient, and highly controlled solution for modern assembly environments.
Pulsing fastening technology is an advanced tightening method that delivers torque through rapid, controlled pulses rather than a continuous rotational force, resulting in smoother and more precise fastening. This approach reduces reaction force on the operator, improves accuracy, and minimizes wear on components and tools. By applying energy in short bursts, pulsing technology helps prevent over-tightening, ensures consistent joint quality, and enhances safety on production lines. Manufacturers benefit from improved productivity, reduced operator fatigue, and greater reliability in assembly processes, making pulsing fastening an ideal solution for high-precision and high-volume industrial applications.
Intelligent click wrenches combine the familiar feel of a traditional mechanical click wrench with advanced digital features that enhance accuracy, traceability, and ease of use. Equipped with sensors and onboard electronics, these tools verify torque values, record tightening results, and provide visual or audible feedback to ensure every fastener meets specification.
Many models feature programmable targets, error-proofing functions, and data output capabilities for seamless integration into quality control systems. Their ergonomic design and intuitive interfaces make them suitable for both production lines and maintenance environments where consistency and documentation are essential.
The newest smart riveting tools from Stanley feature a built-in controller that delivers real-time monitoring and complete traceability without the need for an external control unit. Integrated sensors track key parameters such as pull force, displacement, and break load, giving instant pass/fail feedback for every rivet.
With programmable job profiles, onboard data storage, and optional wireless connectivity, these tools streamline quality assurance while improving flexibility on the assembly line. Their cordless, ergonomic design adds mobility and operator comfort, making them ideal for modern, data-driven manufacturing environments.
At Ansomat, we understand that operator comfort and safety are essential to maintaining both productivity and quality on the shop floor. That’s why our ergonomic solutions are designed as the perfect balance between proven durability and engineering precision.
Moreover, these systems provide the full range of motion required to perform any assembly or fastening task efficiently and safely. By minimizing physical strain and improving tool handling, operators can work with greater focus, consistency, and control, especially during repetitive or high-torque applications.
Depending on your specific requirements, our standardized ergonomic arms can be customized or adjusted to match your production setup. As a result, workers can use heavy or high-torque tools with improved stability and accuracy, significantly reducing the risk of fatigue or musculoskeletal injuries.
In many assembly environments, not all components are easily accessible for tightening or fastening tasks. For example, in applications such as the swing bearing of an excavator, operators often face restricted access to bolts and joints located in tight or obstructed areas. In such cases, conventional tools and setups may be insufficient to reach these points safely and accurately.
To address this challenge, Ansomat offers a range of accessibility solutions specifically engineered to reach the most difficult and hard-to-access fastening locations. With our innovative designs, operators can tighten bolts in deep recesses, narrow cavities, or complex assemblies without compromising torque accuracy or safety.
Furthermore, our accessibility systems are available in both fixed and mobile configurations, depending on your production layout and mobility requirements.
Choosing the right fastening tool depends on your application's requirements for accuracy, process control and traceability. While all three tool types are designed to tighten threaded fasteners, they differ significantly in how they measure torque, monitor the fastening process and support quality assurance.
