I have a job where I need to install ten 32" LCD tv's weighing approx 37 lbs onto concrete cinderblock. The mounts come with options for concrete, but I was wondering if anyone has ever used tapcon screws for this type of application? Will they hold as well as other options? I would like to use 4 tapcon screws per mount. The mount I will be using is the standard peerless tilt mount for 32" tv's.
