I have read and searched but am still confused, I am mounting a 50in samsung plasma over a brick fireplace, what type of bolts should I be using? should I use the brick anchors pictured here? thanks

A correct answer to this question means a better understanding of how you intend to mount. Are you using a bracket? Is there a cantilever arm on your bracket? How much does your TV weigh and what are its dimensions? Is the TV supported at the bottom on a mantel? Also, a pic of your fireplace will help, too.

I dont have a pic of the fireplace but it is a standard brick fireplace (I can get a pic), the bracket is this one http://www.monoprice.com/products/product.asp?c_id=108&cp_id=10828&cs_id=1082801&p_id=3900&seq=1&format=2

and the tv is this one http://www.overstock.com/Electronics/Samsung-PN50A450-50-inch-720p-Plasma-TV/3293341/product.html
the weight is less than 100lbs.

With that type of bracket, I recommend that you use Tapcon screws. Also, if you are trying to attach to a fireplace, DO NOT drill into the brick themselves. Always drill into the mortar. Two reasons for this. I have seen holes drilled into the brick cause cracks in the brick when the screws are attached. Second, if you want to take the bracket off, it is easy to patch mortar, but nearly impossible to patch brick without the patch showing. Even if the bracket attachment holes do not line up with two rows of mortar, do not drill the brick. Drill a new hole in the bracket that will match a second row of mortar. The key to Tapcon screws working properly is the correct drill bit and the correct depth. I recommend using (4) 1/4 x 2 3/4 long hex screws. Check the load rating on the box to be sure. If you want to feel safer, you can always go with more screws. Don't forget the flat washers. Tapcon screws are available at most homecenters. You will also need the special drill bit for this screw. It is usually hanging right next to the packages of screws. You will also need a hammer-drill to drill into masonry.

You can use the screws you listed in your first post, but hey are a bit overkill for the size TV you are mounting and they leave very large holes. With expanding type anchors like this you can crack the masonry. You may also want to take this down someday and smaller holes in the mortar are easy to patch.

Good luck and post back how it goes.

thanks for the information, I will keep you posted.

I decided(well my sister-in-law did) to go with this bracket http://www.monoprice.com/products/product.asp?c_id=108&cp_id=10828&cs_id=1082806&p_id=3725&seq=1&format=2
One question, I thought the mortar was the weaker part and that you should not screw into it, also do the tapcon screws go in alone or do I need a concrete anchor? thanks

When using an articulating bracket, mounting through the mortar is asking for disaster. Mount the bracket to the brick. Make your holes precise, via drilling with progressively larger size masonry bits.
Use the bolts that you posted, in the 1/2" size. For added peace of mind, you can slather the bolts and holes you drilled in the bricks with the strongest epoxy that you can find. I don't really think that this is necessary, but I do it, and sleep better at night :).

I do all sorts of display mounting to stone, tile and brick fireplaces.....

Good Luck!

Thank you, fitero

First are you absolutely sure it's real brick? Most newer construction is not true brick (and those that do have it recently usually just call their 'guy' up :) )

Second, are you absolutely sure you want it over the fireplace? Where is the current set at? I have seen more over fireplace installs that were crappy than ones installed on another part of the wall.

However in the recent homebuilder bloom tons added in fireplaces on viewing walls. In a walk-through the idea was golden, when living in it; not so.

I am installing for my sister-in-law, she just bought a 1940's brick home, yes it is real brick. She now says maybe she wants it on the wall (not so much a pita for me) so we will see, the bracket is due in early next week and I probably wont install until the weekend of dec 6th, I will keep you posted and thanks for all the help
