    Look carefully at the thread. Does it look to be tapped to the same depth at both ends and check there's not a significant burr on the difficult side.

    Are you tapping these holes yourself? If you are tapping yourself do you have a set of 3 taps or are you using just one tap? If you are using a taper or second then you will need to run it almost all the way through to ensure you cut the full thread depth right through the hole.
