Re: Mounting TV on brick fireplace - what screws and where? I'm not going to start a new thread. Hanging a TV above a fireplace isn't the best location as already explained.
That being said:
Avoid Tapcon like the plague. Use properly sized (for weight) screws and anchors.
Just an example: If your TV and mount weigh 100#, and you have 4 screws rated at 40# each (160# total), you are golden.
DO NOT use the mortar joint. Drill into the brick. I've been mounting heavy expensive stuff onto brick for decades. Trust me.
A hammer drill will make for quicker work.
A regular carbide masonry bit will work if it is sharp (still has it's edges) and you have a lot of time.
I used to drill the shit with a star drill and hammer - now that was time consuming.

A quick note about this:
For a TV mount, the tension (pull-out) rating of the fastener doesn't have much to do with the weight of the TV. TV mounts with arms that allow the TV to swing out from the wall will put far more tensile load on the top two fasteners than the raw weight of the TV. If we just divided the weight of the TV by four to determine the fastener rating, you could mount a 4000 pound TV with 3/16" tapcons.
Check the instructions on your mount to see what fasteners you need. |

kudos:1 | And speaking of fastener pull-out, I wonder just how much strength a sand mix grout joint has to offer compared to the brick.
I am willing to bet certainly a lot less than the brick itself using the exact same anchor/fastener combo.

Put a good anchor in it instead of a tapcon.
SE14 1/4'' - 20 x 1-3/8'' should hold the bracket very well.

Annapolis, MD | Yeah, I'd be tempted to use an oversized fastener in the mortar joints rather than drilling through the brick. Holes can be patched up much more easily that way if you want to get rid of the TV. As noted, the mortar joint will not provide the same strength that most solid brick will, but a 5/16" or 3/8" lag with a lag shield or plastic insert is pretty much guaranteed to hold a TV mount. The ones jack linked are great, but hard to get out in the future. |

The point of using the space between the bricks is to fill it with fastener which is touching brick above and below, which are the directions in which the force of gravity will be exerted. There's mortar on the left and right of the anchor, but there's not much horizontal force at play, so no biggie. Bricks have voids inside and are thus likely to crack, and patch work (matching shades) is no fun. |
