Review on Concrete Masonry Bridge Fasteners by Phillips by David Dober

I like the packaging, but the 5/32 bit that comes with it seems too small for an effective anchor. I drilled 6 holes and attached a light plastic lamp body to the outside brick wall. Whether I was drilling mortar or the brick itself, there was no solid anchor in the wall. I tried a slightly larger bit with an even worse fit, so I tried a smaller one and the screw wouldn't go in. Anyhow, I hope this helps.
