Bolted joint: Design, selection
& optimization according to VDI 2230

In this e-learning course developed by engineers, you’ll learn step by step how to properly calculate, evaluate, and optimize bolted joints in accordance with VDI 2230 Part 1. The course is available entirely online and is ZFU-certified, allowing you to learn at your own pace from anywhere and immediately apply what you’ve learned to design, calculations, and project work. Take advantage of our more than 30 years of experience and take your knowledge to the next level.

In the subsequent live session, you will have the opportunity to direct your questions straight to our experts. This ensures that what you have learned is reinforced with practical relevance.

This seminar is independent of MDESIGN software.
No installation or use of the software is not required.

VDI 2230 Part 1:
Current cerification and calculation

Find out how to calculate a highly loaded bolted joint in accordance with VDI 2230.

Loads on a bolted joint

What kind of stress is acting on my screw? What conclusions can I draw from this? You’ll learn all of this in our seminar.

Tightening and assembly procedures

For specific tightening and assembly techniques, influences and processes are precisely analyzed and described in order to achieve optimum results.

Securing Screw Connections

The goal is to ensure the highest possible reliability for the bolted joint. Learn all about the latest findings on this topic.

Course & Live Session

Watch this short introductory video to learn about the opportunities and benefits the course has to offer, such as:

  • Learning anytime, anywhere
  • Practice interactively and deepen your knowledge (multiple choice)
  • Complex knowledge explained in a practical way (VDI-compliant)
  • Pedagogically reviewed and easy to understand
  • Download data sheets – Knowledge available offline too
  • Approved by the “State Central Office for Distance Learning”

All participants will have access to a monthly Q&A session with our VQWS-certified experts. During these sessions, they can discuss specific problems from their own projects—ranging from questions about friction coefficients and borderline cases to the interpretation of stress states.

This way, you can not only make use of the course content, but also clarify specific situations from your day-to-day work.
