Hi Guys,

I've run into a little trouble on trying to do a coincident mate on a screw and hole. When I try to do the coincident mate, I get an error saying unable to mate the selected entities.

If I just move the screw in place it looks like this. 

The hole size is a M3 CSK. I changed the default outer dia. from 6.3 mm to 5.6 mm. The screw I am using is found here: McMaster-Carr 

I've done this before, for example, doing a coincident mate between this screw and hole and haven't had an issue before. The Hole is a M2.5. And I also changed the OD to 4.7 mm (default 5.5 mm) as per screw specifications. The screw can be found here: McMaster-Carr 

So not sure why it isn't working with the M3 screw as shown above. Any help would be greatly appreciated!

Regards,
