The magnet does not fit inside the washer hole on mine. The magnet is so strong that once you get it near the washer, it just sticks on there. You should be fine with the smaller magnet, just experiment where to glue it. I would guess the top portion of the cap.
Thanks for the warning about pacemakers. Magnets are in so many things. My friend had her daughters necklace in her pocket and got stuck to the counter at Domino's while picking up her pizza!
