For outdoor, damp or corrosive work, use a stainless-steel or galvanized anchor instead.\"}},{\"@type\":\"Question\",\"name\":\"Do I have to blow the dust out of the hole first?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. The channel between the threads gives drilling dust somewhere to go, so it cannot obstruct the thread. Clearing the hole with compressed air gives slightly better results but is not required.\"}},{\"@type\":\"Question\",\"name\":\"How deep do I drill?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Drill about 1\/2 in. deeper than the screw needs to go, so drilling dust can settle below it.
