Specification

Notice

The pressed-on flange generates a lower surface pressure, which helps to prevent stress cracks.

Zinc-plated drilling screws must only be used where dampness is not to be expected.

For connection elements with a construction product approval, the approval, and in particular Part 2 "Special regulations", must always be observed.
