Catia counter sunk screw constraint

Hello,

I am trying to apply constraints to a countersunk screw.

1- I apply “contact” to the conic surface of the head of the screw and the conic surface of the hole.
Afterwards I wanted to apply “coincidence” to the axis of the screw and the axis of the hole. But I am getting that they are redundant.

2- I don`t know if the right solution can be to apply
- “contact” (like in 1) and “angle” constraint to the planes of the screw, with the planes of the part where the holes are.
- “coincidendce” (like in 1) and “angle” constraint to the planes of the screw, with the planes of the part where the holes are.


Thanks a lot

A Contact constraint between the screw head and the hole countersink is all you need, unless you want to also constraint the angle of the screw rotation about it's axis. A contact constraint between two cone-shaped faces defines 5 degrees of freedom, including the coincidence of both axis.

There are several ways you could constrain the screw to the hole, but I think your #1 method is the best.
