Err, I know. This is how I had used them previously. But this time,
fixing 4x2 to a reinforced concrete wall they just wouldn't hammer. (In
all cases I ensure the plastic plug is snug to the timber surface before
having a go.) Bitter experience proved that hammering them first was a
disaster. They just bent and at that stage screwdriving was impossible.
I can send you the pics if you like ;-(

I must admit to being baffled. If your correct sized drill goes in far
enough - and the hole isn't left full of dust or rubble - I don't see how
the fixing can fail to hammer in fully.
