OK this is shockingly basic to most of you I'd think, but it really ran rings around me, not having any way of knowing this stuff. Every guide I've seen says to drill the hole the size of the rawl plug, which I obediently did. So then I put my screws in, my cordless driver jams so I flex the muscles, put in a manual, lean against the screw and twist... it snaps.
I do this 5 times in different spots until having used all the good spots up I end up hacking out the screws, refilling with concrete and putting easi fill over the top of it.
So, in despair I phone a builder friend. We have a long conversation. He too is telling me to drill the hole the size of the rawl plug. I say "can't I just drill it the length of the screw so they don't snap?". "What?" he says, "The screw isn't the same length as the rawl plug?". Nope, I says, and the screws came with the rawl plugs too, from rawl plug the company as in John Rawlings. "Well drill the hole the bloody length of the screw then."
So I does. It works great. If any of you happen to read this who have a guide saying to make it the length of the rawl plug shouldn't it say make it the longer of the rawl plug or the screw? Or was I just lucky? They've got quite a load on them, probably 20 kilos a hole and they are all holding fine.
