Knowledge

Most of the questions we get are not about which product exists, but about what the difference between two alternatives actually means. When is powder metallurgical steel worth the extra cost, what separates torque tightening from bolt tensioning, what tolerance does the functional surface really need.

Here we collect the answers so they can be read without picking up the phone. The glossary is in place and explains the terms that recur across the range. Guides going deeper into individual material choices are added over time.

If you cannot find what you are looking for, asking us directly is often quicker than searching on.
