What is the best screw for soft materials?
Coarse screws tend to be best suited for soft materials. The long gaps between the threads will provide more grip in this environment, binding the two materials together strongly. You might also want to consider using a fine screw. In this model, the threads have been put very closely together.
Why are coarse threads better than serrated ends?
Coarse threads tend to have more space between each thread. This can make it easier to screw into the materials. To make the process even easier , some screws use serrated ends. These feature sharper edges, so they can cut through thick materials faster. Coarse screws tend to be best suited for soft materials.
What is a stud finder?
A stud finder device will allow you to pinpoint the stud locations. You should also make sure that you are tightening up the screw enough. This will determine how tightly the materials have been bound together. The more force you use putting it in, the more power will be required to remove the screw.
