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.
Bolted joints – quality monitoring with ANALYSE systems from Kistler

Joining two or more parts with a bolt: it sounds perfectly simple in theory, but it often presents a challenge in series assembly. The objective: to guarantee consistently high quality in a cycle throughout a lengthy period. Functional characteristics such as the friction coefficient, preloading force and torque of the bolted joint are some of the most critical quality factors in the production process. And that's why they have to be fully verified and documented – from start to finish. Highly flexible modular test systems for quality monitoring from Kistler determine the functional characteristics of each individual fastener – from measurement and control of the bolting process through to comprehensive documentation of process parameters. The benefits: consistently increased process reliability, optimized resources and sustainable quality assurance – to ensure your success.
Your benefits of our ANALYSE systems for quality monitoring of bolting processes:
- Lower costs
- Optimized fasteners
- Enhanced efficiency in the bolting process
- Complete documentation
- Protection against product liability cases
- Reproducible test processes
- Traceable results
- Compliance with standards
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

Each INSPECT system from Kistler is a complete inspection system to determine process characteristics in fastening technology. From monitoring of the fastening process through to comprehensive documentation of the process parameters and results: these systems cover the entire range of requirements according to VDI/VDE 2645 Part 3 for a vast variety of process inspections. End-to-end inspection and documentation provide proof of the quality of the threaded joint. This allows targeted monitoring of tolerance limits, and process deviations can be detected at an early stage.
Quality assurance for fastener assembly – advantages of in-process inspection systems from Kistler:
- Reduced costs
- Fault detection with immediate quality corrections during the process
- Optimized bolted joints
- Enhanced efficiency in the fastening process
- End-to-end documentation
- Protection against product liability cases
- Reproducible inspection processes
- Traceable results
- Compliance with standards

Kistler offers an extensive range of products to monitor threaded fastener tightening processes and to assure the quality of bolted joints. Piezoelectric reaction torque sensors deliver precise torque measurements so that handheld screwdrivers can be reliably calibrated. Friction values can be measured for subsequent verification of the strength of bolted connections. Integrated solutions with rotating torque sensors allow direct measurements during fastening.
Quality assurance for threaded fastener tightening processes – advantages of monitoring systems from Kistler:
- Sensors with overload protection
- Piezoelectric sensors with wide measuring ranges
- Straightforward retrofitting
