Hey guys,
Purchased some blinds to install myself into the window reveal. My house is a 2015 build that I believe has concrete lintels. When I moved in I had vertical blinds installed and the brackets are fitted using just these self-tappers (see image). I recall trying to drill into the mantel myself one time and making a horlicks.
Are these self tappers just screwed in or are the holes predrilled?
