Drywall screws are simple fasteners with one job. But before contractors and homeowners get to work, they need to answer a few questions to understand which type they need.
What is the framing made from? How thick is the board? Does the screw need to start in wood or light-gauge metal? Retailers can help their customers by stocking a complete range of everyday drywall screws and providing guidance about which screw to use.
1. Start With the Framing Material
Framing material is the first decision because wood and steel hold screws differently.
- Use DWC coarse-thread drywall screws for drywall to wood framing. The wider thread pitch bites into the wood and helps pull the board tight to the studs.
- Use DW fine-thread drywall screws for fastening drywall to light-gauge metal. Fine threads give more engagement and reduce the risk of chewing out the stud.
- Use S12 self-drilling drywall screws when the steel is heavy enough to need a drill point. A sharp-point drywall screw may still start, but it is not the right solution.
2. Match the Length to the Board
A drywall screw needs enough length to pass through the board and penetrate the framing. Extra length adds cost and increases the chance of hitting something behind the surface.
For common interior drywall work, 1-1/4″ screws are a standard choice for fastening 1/2″ drywall to wood framing. Thicker board, multiple layers, ceilings, steel framing, and rated assemblies may require longer screws.
3. Choose the Right Point Type
Standard sharp-point drywall screws handle most ordinary wood and light-gauge metal applications. Sure Drive CDW Type-17 drywall screws add a cutting point for tougher wood conditions. The point gives them a cleaner start, where a standard sharp point may struggle.
Self-drilling drywall screws are for steel applications where a sharp point cannot reliably pierce the framing. The drill point creates the hole before the threads engage.
4. Set the Correct Driving Depth
Drywall screws have a bugle head with a curved underside that helps the screw seat into drywall without cutting the paper as a flat countersunk head would. It should sit slightly below the face of the board so the joint compound can cover it.
A proud screw head will catch the finishing knife when joint compound is applied and may show through the finished surface. An overdriven screw will tear the paper and weaken the connection. Don’t rely on a screw that has been overdriven. Drive another screw nearby to compensate.
5. Use a Driving Method That Can Control Depth
A drywall screw gun with a depth stop gives installers the most repeatable control and reduces the need to judge every screw by feel. A standard drill can work for small repairs, but it takes more care. An impact driver is usually a poor choice because the additional torque makes it easier to overdrive screws.
Choices Customers Often Overthink
Gauge
Use the gauge specified for the job, but do not treat the diameter as a fix for the wrong screw. Most ordinary single-layer drywall work uses smaller drywall screw diameters.
Pre-Drilling
Pre-drilling is usually unnecessary in drywall work. If customers want to pre-drill because screws have been hard to start, the better advice is to make sure they have the right point type for the substrate.
When Are Drywall Screws Not the Answer?
Drywall screws are designed for fastening gypsum board to framing. They are not general-purpose structural fasteners. For example, drywall screws should not be used to hang cement boards or fasten decking.
Cement board is often used in damp conditions, so the screw needs a corrosion-resistant coating. And unlike bugle-headed drywall screws, cement board screws need heads that seat flush. A drywall screw will not sit correctly or develop sufficient holding force.
Likewise, deck fasteners have to survive weather and contact with treated lumber. A drywall screw may be sharp and easy to drive, but it is not intended for those conditions.
That said, Sure Drive drywall screws can also be used in non-structural interior fastening where the material and load are appropriate. They can fasten combinations of wood, metal, plastic, fiberglass, and other materials, but the application still has to suit the screw.
