Did not know customer wanted magnetic latches, so I built door in such a way that the only way I see is to bolt metal piece that makes contact with magnet. Problem is that the head of the screw is holding the door away from the carcase of the small cabinet. Is there a glue I can use to hold that metal piece in place instead of using a screw? If so, what kind do I need to use? I know I can super glue it, but the glue, over a period of time, will not hold. Thank!

Is the plate thick enough to counter sink the screw? Or, maybe, use another magnet counter sunk into the cabinet frame. If the hole for the second magnet is a tight fit, super glue should keep in place

Sand the metal down with say 80-100 grit, no more than that.  This will give more surface area for a dab of epoxy to hold onto it.  Will last long time.

I usually drill a hole the size of the magnet and use epoxy to glue it in. With Epoxy you do not need to rough the surface usually.

 

Super glue will give way in the future. I was thinking maybe an epoxy glue might be more permanent. What do you think?

Thanks for the suggestions. Merry Christmas to all, and to all a good morning!

Thick epoxy will hold better.

I have some tubes of black marine epoxy, so I ground away the hole where screw goes through in the flat metal pieces. Then, I put the marine epoxe on the metal pieces, and found a couple of small places that did not have the epoxy on it, and I dribbled a small amount of super glue. That gave it both a quick grab and also a long-lasting glue as well.
