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.

Bolt size is M4 by 16mm length.

Hello,

There are different types of stands as well as the screws vary. It is by the exact type of stand we can provide a screw size.

Another solution is for you to try to reach the dealer that supplied the TV stand to you, so as to get the exact screws that came with the stand.

Take care and good luck
