Rawlplug XPT Throughbolts M12 x 180mm Pack of 10
Used 20 of these to secure shed base into concrete and blockwork. Used Dewalt 12mm sds drill, fixings were tight in the hole and all held well when drawn up.

Drilled the right hole with a De-Walt 12mm masonary bit fixing loose in hole wouldn't bit despite solid tapping others that did hold if tightened hard broke the bit that epands in the wall... all in all a waste of money and I would recommend using resin and threaded bar as I am now going to do...

Good solid fixing
I used these to secure a 3.5m ledger board to a stone wall ... the board was to support a raised deck. The fixings fit tight to a 12mm hole and lock well with a few good taps. The board was solidly held when fixed.
