I am in the process of removing the old mast step on my H27. its held in place by 10 countersunk screw head M12 mild steel bolts. I can see where 8 of the come through but not the front 2. 
The 8 visible ones go through the top of the mast step, through the coach roof, and then through a steel plate that sits inside the boat in the deck-head. i have managed to undo 7 of the 8 visible nuts, but the won't push out, even with some persuasion with a hammer, so i am guessing that they are threaded through the metal plate, and that the nuts are locking nuts. I should be able to deal with that, but the mystery is whether or not the other 2 (furthest forward) bolts are locked or just thread into the steel plate, as there is no visible evidence of locking nuts, just a smooth deck head.

Would be grateful for any input/information

Well, it turned out that the bolts wouldn't shift because they were corroded into the wooden mast step. Eventually removed with a combination of sawing, hammering and drilling. Now replaced with a new teak mast step, bolted down with M12 A4 stainless carriage bolts, all bedded down on Sikaflex
