In demanding fastening technology, the validation of torques and friction coefficients is the basis for safety and process stability. At hytool.de, you not only receive high-quality tools but also the appropriate testing technology. Our screw and friction coefficient test benches are developed in close cooperation with our sister company VMA engineering GmbH and manufactured individually according to your specific requirements.

Precision through VMA engineering's engineering expertise

While hytool.de is your expert for providing bolting equipment, VMA engineering GmbH provides the technological foundation for our testing systems. As specialists in bolted joint analyses and fastening technology, VMA develops test benches that are precisely tailored to your parameters – from sensor technology to evaluation software.

Our portfolio in testing technology:

• Friction coefficient test benches (according to DIN EN ISO 16047): Precisely determine friction coefficients on screws and nuts in-house. We adapt drive power, sensor technology, and test bench size individually to your application.
• Torque & screw test benches: Validate your bolting processes under real conditions. Whether laboratory application or production-related testing – we build the solution you need.
• Intelligent sensor technology: Discover torque and force sensors with modern digital interfaces for seamless documentation and maximum measurement accuracy.

Services & Analyses: More than just hardware

Through the synergy with VMA engineering, we offer you much more than just the sale of test benches. Use our expertise for:

• Bolted joint analyses: We simulate your original bolted joint on our in-house test benches.
• Calculations according to VDI 2230: Professional design of your bolted joints.
• Individual special construction: Do you have a complex measurement task? We develop the right solution together with you.

 

Pro tip for quality assurance:
In-house testing vs. service: For high testing frequencies, your own test bench quickly pays for itself through shortened development times and direct access to measurement data. For one-time validations or complex initial sampling, the services of VMA engineering are available to you.
