Drywall anchors are used to holding screws in place and prevent them from coming out and damaging your walls when you hang heavy objects on them. They can also replace toggle screws if you want something more decorative than just a screw head sticking out of the wall.
A good drywall anchor should be durable and made of high-quality materials. It should also be easy to use and install. With so many different types of products available today, finding a suitable product can take some time.
