"I used these to fix some kitchen wall cupboards to a dry lined wall, I'm not sure if that is what they are intended to be used for but they did the job very well. Reasonably priced (well quite cheap really) I would certainly use them again."
"Bought these to fix 2x3 to a concrete block wall. Unfortunately, despite drilling the correct size pilot holes, two of the screws have snapped off on tightening. The others have gone in ok, and the price is good."
