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.

It's not unusual for someone new to precision fastening to complain about the lack of precision of electric screwdrivers when dealing with hard joints; in reality, a smart fastening system with torque control like Kolver's K-DUCER can be easily programmed to achieve superior precision even with the hardest joints.
As we have seen before, a hard joint is characterized by minimal movement between the mating surfaces during tightening, resulting in a rapid increase in torque once the fastener makes contact. This abrupt torque rise can lead to over-tightening, potential damage to components, or inconsistent clamping forces when working at too high of a speed, due to the inertia of all the rotating parts.
The K-DUCER addresses this challenge through its downshift function.
