    If I have a M10 hole thats been tapped, should I be able to put the bolt in either side or just the side it was tapped from. Never dealt with tapping until now :D

    If you've tapped it all the way through with a plug tap, then definitely not a problem. If it's only been cut with a taper tap, then the thread may be incomplete toward the bottom of the hole, which would impede inserting the bolt from that side.

    I had to google it but it looks more like a plug. The bolt goes in fine from the tapped side but needs a spanner to turn the other way, should I just keep pushing or am I missing something?

    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.
