We offer an extensive portfolio of test and analysis systems. They analyze the functional characteristics of bolted joints (such as the coefficient of friction, preloading force or torque) and also bolting tools; they capture all the measured values and provide a clear presentation of the documented results. These systems allow targeted monitoring of tolerance limits, and they ensure that process deviations in fastening technology are detected at an early stage.
Maximum quality and process reliability in fastening technology

To maximize quality and cut costs, fastening technology must be continuously monitored and tested. In virtually every sector of industry, assembly with bolts and screws is one of the most frequently used joining processes in manufacturing. It’s crucially important for bolted joints to function safely and reliably – otherwise, there will be the risk of recalls and additional costs.
Torque tool testing and calibration prior and during assembly

Regular torque tool testing and calibration is essential whenever reliable bolted joints are needed in today's industrial production processes. Not only do torque tools such as torque wrenches and rotary nutrunners have to be calibrated and certified prior to assembly: they also need repeated inspection and verification as the assembly work proceeds. The objective: to maintain continuous high tool performance in order to achieve optimal assembly results and meet specified standards.
Advantages of our inspection systems for torque tool testing and calibration:
- Dynamic inspection of torque tools prior and during assembly
- Reproducible conditions for calibration or certification of bolting systems
- Calibration of torque wrenches to ISO 6789
Do you have any questions about testing and calibrating, respectively certifying, torque wrenches and nutrunners? We'll be happy to assist you.
Efficient in-process inspection in fastener assembly
The INSPECTOR electronic torque wrenches are hand tools designed to fasten and check bolted joint connections by following various procedures. The measured values can be evaluated and archived using the software platforms CEUS and testXpert.
