creation of bookshelf screws

[french]

Good morning
I have to put in a set of screws but there are no bookstores, I could open the existing ones and change them in what I need, but I don't know how to do it.
Thank you.
Hi.

What do you mean by library screws? family table, models cadenas, etc.

when I put together a "pro-library" screw select the type of screw m..x. However, there is no shortage of measures that concern me.

pro/library is nothing but a display of a set folder in the config.pro. then if you lack values you have to change the original object (probably the family table).
