The next time you need to repair or replace a piece of drywall and will be screwing it in place, don't just assume you can pick up the first box of screws and everything will be great. If you want to be sure that the panel stays in place, without having any holes, and no broken screws, you need to get the right type. Here are a few tips for making sure your walls always look great.

Size 

Drywall comes in two common thicknesses. You will either have 1/2 inch or 5/8 inch panels. You can use the standard 1 5/8 inch drywall screw for either size panel. However, it can be difficult to sink in the last 1/8th of an inch so that it does not stick out, leaving a noticeable lump in your wall. If you are using 1/2 inch panels, buy a small box of 1 5/8 inch screws and try them out. If you have trouble getting them in far enough, go with a shorter screw. For the thicker panel, you should be able to get them to sink in without any problem.

Coarse or Fine Threads

When you have wooden studs as the frame for the room, you need to use screws with a coarse or wide thread. This will ensure that the screw bites into the wood in a way that will pull the drywall taut against it. If you are using metal framing, get fine-threaded screws. Not only are fine-threaded screws self-threading, but they will also keep the metal from being damaged by a wider thread. Once the hole is damaged, it won't be able to hold the drywall securely.

Coatings

While it might not seem like the screws will get much exposure to the elements, you would be surprised at how easily they can corrode or rust. One way to stop this is by purchasing screws that have an anti-corrosion coating on them. This coating may also make it easier for the screw to glide into the stud.

If you feel overwhelmed when trying to pick out the screws for your project, talk with the drywall screw supplier. Explain what your project is, what type and size of drywall you have, and what tool you will use on the screws. Once you have determined which screw to buy, they can help you figure out how many you are going to need so you won't have to come back to the store for more in the middle of working.
