What size screws do I need to mount a 55 inch TV?

I am mounting a Samsung TV to the wall. I purchased the best selling TV wall mount kit. I have everything setup to mount the TV. I have the tools and all the hardware needed. The problem I am having is the screws that came with the TV mounting kit do not seem to fit into the back of the TV. The screws that came with the TV mount kit are too wide. I am not able to secure the TV to the mounting bracket. Am I missing something? How can I find out which type of screws fit into my TV to hold the bracket?

Screws for Mounting TV to Wall Bracket:
The most common screw for securing the TV to the wall bracket is an M8 screw.
The other screw sizes for some TVs are M4, M5, and M6.
The length will be determined by the type of TV you have.

The length of the screws will be in conjunction with the depth of your specific TV.
The most common M8 screw lengths for TVs is 10mm, 12mm, 20mm, 25mm, 30mm, 40mm, 50mm, and 60mm.
There are some TVs that require a longer millimeter screw.
Most screws will need to have a spacer on it to allow airflow behind TV, etc.
See image below to see spacers on TV screws…

To find the depth or length of the screw you need:
Put a pencil or toothpick down into the screw hole to find a rough estimate of the depth or length of screw needed.
You can also purchase a Universal TV to Wall Bracket Screw Kit and have all the screws needed including spacers and washers.
The screw that holds the mounting bracket to the TV should have at least 5mm of threads into the TV to hold it secure.
Be sure you add the depth or thickness of the TV mounting bracket when finding the correct screw length.
