What to know
The software relies on the INDEX database of CE-marked screws, so the result is a selection from its catalogue. Even so, there are almost no free tools for timber connection design, so it is useful as a point of comparison for a hand calculation too. It does not analyse the whole structure — the forces in the connection come from analysis software.
