When mounting items on the wall, it is important to get a firm connection. There is the danger of property damage, especially when something expensive like a TV is hanging on the wall, and you also have the risk of someone getting hurt when the item falls on them. This is why there is a need to be careful when mounting something, especially when doing so in drywall.
Drywall is a very useful building material, but it is not made for mounting items. This is why anchors are used instead to give some extra support when hanging anything on drywall. There are anchors that are made for a wide range of applications and varying weights, so you should make sure you get the right ones for the item you want to mount. You should also be aware that there is a limit to how much the wall can carry, and if you try to mount something that is too heavy, you could cause major damage to your wall.
