What is the best way to secure an open hook bolt in the wall? I want to secure a washing line to it.

Hi Jane, the 6mm open hook expansion bolt requires a 12mm hole to be drilled into the masonry to install it. You would need a cordless or corded hammer drill and a small 4-6mm masonry drill for the pilot hole, then 12mm for the 2nd hole. You insert the expansion bolt then tighten the nut to expand the fastener into the wall. I trust that this helps?
