I’d recommend checking out Ace Hardware. They are well known for carrying speciality hardware. As far as the type of screws required, it looks like that depends on the way you want to mount the TV onto the wall. Google AN-52AG4, the model of the wall mount recommend by Sharp. You should find a link to files.sharpusa.com that will take you to the wall-mounted manual which tells you the type of screws you’ll need. If you aren’t using the recommended wall mount, refer to the installation instructions of the wall mount you are using to find out the size of the screws you need.

First of all find out what size mount is on the TV. On the back of the TV you should see 4 screw holes to take the bolts of the stand. You can measure the space between the holes. Then you can search for a mount that will take that size. If the TV is big you will need a very strong wall mount.
When you get the mount it should have instructions for mounting it. But make certain the wall you are fixing it to can take the weight and is stable. Fix the mount to the wall, make certain that you use the correct screws and plugs for the screws. You should be able to tell if the mount is secure enough. If you have any doubts, get somebody in to do it. The mount will come with the correct fixing screws for the TV. You will need two people at least to fix a smaller TV to the wall and two people to hold a big TV while a third screws the mount to the TV.

The 3 most common sizes for the bolts to mount the wall mount to the TV is either M8x20mm or M6x20mm or M4x20 depends on the size of the screen. This site has a chart that will show you what to look for, for your TV M6x20mm TV to Wall Mount Bracket Phillips Bolts Screws Stainless VESA 200

Not sure what you are asking. Are you looking for the screw for the attaching the mount to the TV or the mount to the wall.
If you are looking for the screw size for the back of the TV, it could be metric size M6 or M8. Just be careful of the length. Too long and you will ruin the TV. Maybe google the TV model and it might show in the owner manual the exact screw to use.

any hardware store will have them bring your tv manual with you it will tell you the spec on the screw to connect to the 4 pre existing nuts on the back of the tv as far as from the mount to wall it will be a standard lag bolt small enough to fit threw the hole and long enough to go threw the drywall and about an inch and a half of the studd 2" to 2 1/2" inch lag bolt will work

The screw holes are metric. The set is supplied with M5x25 screws to attach the pedestal, so the wall mount screws will be in that same range.
