Limiting a screw in a larger hole

Hello
Let's take the example of an M10 screw in a hole of Ø14, is there a kind of limit, or a combination of constraints, for the screw to be free in the hole without coming out? It must be free, not just tangent inside the hole.
I'm on SW 2021, there may be a solution in a newer version.
Thank you for your answers.

Hello;

The ideal will be to use the constraints of Grooves (but I'm not sure if it works on cylindrical holes... to be checked).
Otherwise, but I find this option very dangerous, in the Solidworks options you can allow offsets on the coaxialities:
See "Allow the creation of misaligned constraints"

or more precisely:

Kind regards.

Hello

With a set 0-4mm limit distance between the axes (screw axis and drilling axis), it works.
There will remain a constraint to be placed for axial displacement.

Thank you for your answers, regarding the groove it doesn't work, it's the first thing I tried before posting, at least on SW 2021 (see on the more recent versions).
I'll try your solutions and dig a little deeper.
