Bolted connections:
Design, selection & optimization

Currently only available in German.

In this MDESIGN e-learning course on "Bolted connections according to VDI 2230 Sheet 1", you will learn how to efficiently calculate, safely design and optimize bolts in a practical way. The course contains everything you need to know about the professional application of the VDI 2230 guideline.

Screw connections are the most frequently used connection technology in mechanical engineering. And yet they often harbor unexpected risks.
Errors in design or assembly can lead to costly damage,
failures or even safety-critical situations.
Learn the necessary specialist knowledge on your own,
to design bolted connections safely, efficiently and in accordance with standards.
