"Used these to fix a timber fence post to a wall. Had no problem with them as long as you use the right size drill bit and screwdriver bit. Went in fine using impact driver. And cheaper than fisher equivalent."
"The screws are too soft by far. Buy Fischer or Rawl products and you will pay aslightly more but they will not fail. Don't buy these - the head is easily chewed out by the driving force. I bought two packs and on the second pack chucked away the screws and used coach screws in the plugs instead of the screws supplied."
