Modbus is a widely used communication protocol in industrial automation. It enables different devices, such as PLCs, sensors, drives, and precision tools like Kolver’s K-DUCER, to exchange data over serial or Ethernet connections.

For automation engineers, Modbus is almost plug-and-play: most Ethernet-capable PLCs and industrial PCs/MES systems already support it.

When it comes to tightening tools, precision isn’t optional — it’s a requirement.
But how can we be sure that a screwdriver or torque tester truly meets the required standards?
The answer lies in certification. But beware: not all certifications are created equal.

In the field of industrial assembly, the reliability and accuracy of torque tools are essential.

KOLVER’s K-TESTER is already a leading tool for torque measuring, but what happens when multiple transducers are involved, and a real-time, streamlined solution is needed?

The answer is the new multiple output connector DOCK08, which allows up to 4 transducers to be connected simultaneously to the K-TESTER.

In bolted joints, the use of washers has become something of a default practice. At first glance, a washer seems like a simple component, just a flat disc placed between the nut or bolt head and the joint surface, but underneath this simplicity lies a complex interplay of mechanics and materials that can make or break the performance of your assembly over time.

Let's then take a look at why washers are used, how they impact bolt relaxation, and why the phenomenon of embedding, frequently underestimated, deserves special attention in joint design.

In industrial fastening, speed is often mistaken as a straightforward way to increase productivity. This assumption, often simplified further as in "doubling the speed will double the output", is misleading, as it disregards the complexities of torque control, joint characteristics, and material properties. While faster speeds can reduce cycle times, they also introduce risks such as thread stripping, cross-threading, and inconsistent torque application. Therefore, proper speed management is essential to strike the right balance between efficiency and precision, ensuring high-quality assemblies while avoiding costly rework and defects.
