When it comes to fastening drywall, the right screws are essential. But finding the ideal screw can be challenging if you don’t know what to look for.
Drywall screws come in an array of lengths, gauges, thread types, heads and points. At first glance this seemingly endless variety can seem confusing.

Length of Screws
Drywall screws, also referred to as sheetrock screws, are used for fastening 1″ drywall onto wood or metal studs. With so many variations available in lengths, threads, numbers, gauges, and heads it may seem overwhelming which type of drywall screw is best suited for your project. Thankfully, though there’s help available if you need it!
Fortunately, there are a few guidelines you can follow to guarantee the most suitable screws for the job. You should take into account the type and thickness of drywall material, the screw head type, and which studs you plan on attaching it to.
Coarse-thread drywall screws are ideal for working with wooden studs, while fine thread drywall screws work better on metal studs. The coarse threads grip the wood and bring the drywall up toward the studs, while finer threads create their own secure path into metal studs.
For best results, use screws that are one inch longer than your drywall thickness. This ensures that they can penetrate into the material without breaking it or sinking beneath it.
A common drywall screw gauge is #6, but other sizes are available as well. Be sure to consult the drywall manufacturer’s recommendations regarding which screws should be used with different thicknesses of drywall.
You may choose stainless steel drywall screws, which offer superior creep rupture strength and are designed for extreme temperatures. Furthermore, stainless steel resists corrosion, helping keep your drywall material free of rust.
Another option is yellow zinc drywall screws with a protective coating to prevent corrosion. These are ideal for installing drywall in humid areas as they help shield the compound from rusting due to moisture present.
Some drywall screws feature small grooves beneath their heads that dig into tile backer cement board to increase their holding power. This is essential since certain types of tile backer cement board contain high levels of alkali that can corrode conventional screws over time.
You may need special drywall screws for curved areas, such as dish-shaped ceilings. Curved surfaces can damage standard screws and cause them to break during installation.
Ceiling Height
Drywall screws should be long enough to penetrate the drywall and securely fasten it to wall studs. Furthermore, they should be driven into the studs at an even depth; this helps avoid nail pops and prevents the drywall from pulling away from its anchors over time.
A common size for drywall screws is #6, but larger sizes may be necessary if working with thicker drywall or metal studs. Some self-drilling drywall screws allow you to push them through the outer paper layer of drywall and into wood studs without needing a pilot hole.
When selecting a drywall screw, another factor to take into account is its material. Most are made from steel but there are also stainless-steel options which offer greater corrosion resistance.
When selecting drywall screws, the type of head you use is important to consider. Many come with Phillips-heads but you may also find Torx and square-drive types. Some drywall screws even feature an “eyeball” or cone-shaped head which helps minimize paper tear when driving in the screw.
When using a drill with a drywall screw, make sure the bit has a #2 Phillips head. Doing this will guarantee that you receive the proper number of threads on the screw.
When selecting a drywall screw, gauge is another essential factor to consider. For most applications, either #6 or #8 size should suffice.
In the United States, drywall screws are typically Phillips-head with a bugle head to reduce paper tearing when driven in. Furthermore, these screws are more common and easier to locate than wood screws.
Drywall screws are an excellent choice when installing ceiling installations or working with metal studs or frames. While they provide a strong hold, they may be slightly more expensive than nails.
When selecting screws for your drywall project, always adhere to the manufacturer’s recommendations. Too few can weaken the joint while too many could lead to mudding.
Popcorn Ceilings
Popcorn ceilings were a popular texture in the 1970s. Not only were they an effective way to conceal drywall mistakes and imperfections, but they also provided acoustic benefits–especially when installed in multi-story homes.
These ceilings featured a blend of vermiculite and polystyrene particles sprayed onto the ceiling for an attractive texture. Not only was this application cost-effective and straightforward, but it also helped drywallers conceal any imperfections.
It was also fireproof, sound-absorbing and durable – however unfortunately it contained asbestos which can be hazardous if inhaled.
If your popcorn ceiling contains asbestos, it should be removed for both safety and added value to your home.
There are several methods to remove popcorn ceiling texture. One option is scraping it away with a 4-inch drywall knife or utility knife; although this can be an involved and tedious project, the end result will be an even surface that makes working and painting much simpler.
Another solution is to apply a fresh layer of drywall over the texture. While this method requires more effort than scraping away at it, it can be quicker and more cost-effective in the end.
Before painting your drywall, be sure to sand it thoroughly so that it is completely smooth. Doing this will reduce dust accumulation on the surface and give your room a fresh appearance.
Finally, adhesive hooks can be used to hang decorations from the ceiling. These work best for lighter items like streamers and snowflakes but may not be sufficient enough for heavier decorations.
When hanging something heavy on a popcorn ceiling, it’s best to screw it into an interior stud rather than directly onto the surface. Doing so will prevent the screw from coming loose and damaging your wall.
Popcorn ceilings are a timeless aesthetic that remains popular in many homes, even though they’re considered outdated by today’s homeowners. Not only are they easy to install and conceal various defects like cracks, holes and leaks – they can also cover up stains for an attractive, low-maintenance aesthetic.
Wood Studs
Wood studs are vertical pieces of wood or metal that connect to form the frame for walls, providing strength and space for wires, pipes and insulation while allowing drywall to be installed atop them. They’re commonly used in residential construction projects as they offer extra support and stability while allowing drywall to be installed over top.
Most non-masonry buildings, such as houses, garages and commercial structures, feature studs in their walls. It’s essential to comprehend how they work if you’re building or renovating a structure.
Understanding how to locate studs is useful when hanging art, mirrors or other heavy decorations on walls. It also comes in handy when working on wall-mounted appliances or fixtures, trim work, repairing drywall or installing electrical outlets.
You can use a stud finder or other device to identify studs on your walls, but you also have other methods available. Tracing a line up the wall and knocking on it should reveal whether the sound made is hollow or solid. Another approach involves using a magnet and flashlight combination to pinpoint where studs are located.
Once you’ve located a stud, install it with a screw. Use either a tape measure, flashlight or electronic stud finder to ensure you use the right size screws in the correct spots.
If you’re building a new home, steel studs are becoming increasingly popular due to their many advantages over wood studs. Not only are they easier to work with and don’t warp or twist during transit like wood studs do, but they’re also durable and come in more sizes than their wood counterparts.
Structural steel studs in your house may seem expensive, but they offer numerous advantages that outweigh their costs. Not only are they sustainable materials, but they’re usually more cost-effective per square foot than wood studs.
Structural steel studs, made of hot-rolled steel, are used in heavy load bearing applications like floor joist assemblies. Their thickness is measured in mils (millimetres), an indication of their strength.
Structural steel studs are typically only used in large buildings due to their strength. While they can be difficult to install, these materials are more resistant to rot and termite damage than wood studs and more cost-effective overall. As a result, structural steel studs tend to last longer than wood ones.
