Drywall screws have become the standard fastener for securing full or partial sheets of drywall to wall studs or ceiling joists. Drywall screws’ lengths and gauges, thread types, heads, points, and composition at first might seem incomprehensible.

• 1/4-inch drywall: Use 1- to 1 1/4-inch drywall screws
• 1/2-inch drywall: Use 1 1/4-inch or 1 5/8-inch drywall screws
• 5/8-inch drywall: Use 1 5/8-inch or 2-inch drywall screws

By way of comparison, screws intended for construction come in a large range of sizes. The reason is that building materials can have a wide range of thicknesses: from sheet metal to four-by-four posts and even thicker. Not so with drywall.

Most drywall installed in homes is 1/2-inch thick. Thickness can sometimes increase or decrease, but only by very little and not very often. About the only time that do-it-yourselfers will need to install thicker drywall is with fire code or type-x drywall. At 5/8-inch, type-x drywall is slightly thicker to slow the spread of flames and is used in garages and walls adjacent to furnace rooms.

Drywall that is 1/4-inch thick is sometimes used as facing for walls and ceilings. Because it is flexible, it can be used to form curves. Still, the majority of drywall installed by do-it-yourselfers in kitchens, bathrooms, and general areas will be 1/2-inch thick.

There are two types of drywall screws: coarse thread and fine thread.

Coarse Thread Drywall Screws

Use coarse-thread drywall screws for most wood studs.

Coarse-thread drywall screws, also known as W-type screws, work best for most applications involving drywall and wood studs. The wide threads are good at gripping into the wood and pulling the drywall against the studs.

One downside of the coarse-thread screws: the metal burrs that can embed in your fingers. Be sure to wear gloves when working with coarse-thread drywall screws.

Fine Thread Drywall Screws

Fine-thread drywall screws, also known as S-type screws, are self-threading, so they work well for metal studs.

With their sharp points, fine-thread drywall screws are best for installing drywall to metal studs. Coarse threads have a tendency to chew through the metal, never gaining proper traction. Fine threads work well with metal because they are self-threading.

• Bugle head: Bugle head refers to the cone-like shape of the screw head. This shape helps the screw stay in place, without tearing all the way through the outer paper layer.
• Sharp point: Some drywall screws specify that they have a sharp point. The point makes it easier to stab the screw into the drywall paper and get the screw started.
• Drill-driver: For most drywall screws, you will generally use a #2 Phillips head drill-driver bit. While many construction screws have begun to adopt Torx, square, or heads other than Phillips, most drywall screws still use the Phillips head.
• Coatings: Black drywall screws have a phosphate coating to resist corrosion. A different type of drywall screw has a thin vinyl coating that makes them even more corrosion-resistant. Additionally, they are easier to draw in because the shanks are slippery.
