Attaching wooden shutters to brick?

Some mortar is harder than others.

I used a hammer drill and drilled into my bricks.

But as Frank says, use the lag shields.

Thanks, I was wondering if I could use the concrete screws. I’l get some lag shields tomorrow. Thanks to all who replied.

Bricks crack easier, mortar works just fine and can be patched. Worked as a professional trim carpenter and we never used lag shields or masonry screws to hang shutters on brick. 1/4" SDS hammer drill into the mortar joint, 1/4" oak dowel snapped flush with hole, stainless or exterior-rated 3" construction screws for the stardard 1x site built shutters, 3/8" sleeved anchors for the big ones made with 5/4 deck boards.
