Bolts are an inexpensive, universally applicable fastening element and part of every machine. A particular advantage of bolted connections is the simple and often repeatable assembly and disassembly.
This is done with the aid of different tightening methods, for example with wrenches and sockets. In combination with a ratchet, large tightening torques can be realized easily and quickly using the lever.
However, it must be noted that both excessive tightening torque, which causes thread plasticization, and insufficient tightening torque, which can lead to insufficient clamping force and can also cause the screw to loosen itself, can have serious consequences. It is therefore essential to determine and maintain the optimum torque.
Specially manufactured digital and mechanical torque wrenches exist for this purpose, which emit acoustic or optical signals when the predefined maximum is reached. For quality assurance and documentation purposes, it is also advisable to monitor the torque and angle during assembly.
In a simple socket adapter, core sensing shows how torque and angle can be easily monitored. Thanks to the integrated coreIN sensor package, more than just the achievement of the maximum torque value can be displayed: The entire measurement curve of the torque and angle can be recorded and evaluated in high resolution. Using the coreINSIGHT analysis tool, irregularities during the tightening process and faulty connections can thus be identified.
The sensor automatically goes into an energy-saving sleep mode, recognizes predefined screwdriving cases and documents them automatically - including export to .csv files.

Especially for special tools, core sensing's technology thus offers great potential for the bolting industry.
