The post bases (Byggmax, 50 cm posts) are in the ground. Now it's time for posts for a 120 cm fence... I'm a bit hesitant - I tested and an M12 fits snugly through the holes in the post bases, but perhaps I should go with M10 instead. Advantages, disadvantages? I think offhand that M12 won't be able to move at all (advantage) whereas M10 might (disadvantage) since the hole is slightly larger than the M10 dimension... What do you think?
