For connecting entire or partial drywall sheets to wall studs or ceiling joists, drywall screws have become the standard fastener. The lengths and sizes of drywall screws and thread types, heads, points, and composition may appear unintelligible at first.
Plasterboard or drywall screws, as the name implies, are used to secure plasterboard and offer a long-lasting fix. Plasterboard screws come in various shapes and sizes, each with its own set of advantages. The following are the most popular types of plasterboard screws:

Fine Drywall Screws
Coarse Drywall Screws
Self-drilling Drywall screws
When attaching plasterboard to stud partitioning, use Drywall Screws. Before you patch the plasterboard, ensure you know what’s underneath it and stay away from pipes, electric cables, and other hazards. Plasterboard screws have positive, countersunk heads and are black.
What Are The Size Considerations For Drywall Screws?
Fine Drywall Screw’s sizes
The size of the plasterboard screw you’ll need is determined by the job at hand, precisely what you’re attaching the plasterboard to. If you’re screwing plasterboard to a timber frame, be sure the screw is long enough to penetrate the wood.
However, when fixing metal studs with plasterboard screws, you can use a shorter screw as long as it penetrates the metal stud. The majority of drywall used in homes is 1/2-inch thick. Thickness can occasionally rise or decrease, but only by a small amount and not very frequently.
The only time do-it-yourselves will need to use thicker drywall is if they are installing fire code or type-x drywall.
Coarse Drywall Screws’ Sizes
For most wood studs, coarse-thread drywall screws should be used. Coarse-thread drywall screws are the best option for most drywall and wood stud applications. The large threads grasp the wood well and draw the drywall tight against the studs.
Metal burrs can embed in your fingers, which is one disadvantage of coarse-thread screws. Working with coarse-thread drywall screws necessitates the use of gloves.
Fine Thread Or Self-Drilled Drywall Screw’s Sizes
Because fine-thread drywall screws are self-threading, they are suitable for use with metal studs. The best drywall screws for installing drywall to metal studs are fine-thread drywall screws. Coarse threads have a habit of chewing through metal and never establishing adequate traction.
Because fine threads are self-threading, they function well with metal. Coarse-thread drywall screws hold in wood better than fine-thread screws.
What Are The Uses Of Drywall Screws?
The primary function of drywall screws is to secure entire or partial drywall sheets to either wood or metal studs. Nail pops can be repaired with drywall screws. If you have an older house, you have nail-pops and see mysterious circular bumps on the walls.
Drywall was nailed with short, wide-head nails before drywall screws became widely used. While drywall nails are still used to fasten drywall to studs, drywall screws have become the standard method of attaching drywall to studs due to the nail-pop issue.
Is It valid To Use Drywall Screws For Building Projects?
Drywall screws are used in some DIY building projects. This is because drywall screws are far less expensive than wood screws; they drive and bite into the wood quite well and are plentiful.
Few fine woodworkers would ever use drywall screws in their work. Avoiding drywall screws is especially vital while working on heavy or even modest construction projects, such as fences and decks.
The consensus is that drywall screws are fragile. They can snap instead of bending. Drywall screw heads are prone to breaking cleanly, leaving the shaft piece lodged in the wood. A headless screw can’t be removed with a screw extractor.
The bugle head is one of the reasons why drywall screws are ideal for drywall. The drywall screw’s curved head is made to crease the drywall’s top paper layer, not for sinking into the wood.
Much energy is exerted when a drywall screw is driven into wood and reaches the head; this must be countered by drill force. This is why so many drywall heads break when driven into wood.
How To Install Drywall Screws?
You won’t need a dedicated drywall screw gun if you’re a DIY person or a casual drywall installer. A drywall screw gun is a specialized instrument for drywall hanging. Most cordless drills are more compact, lighter, and have lesser torque.
While screw guns are fantastic for driving drywall screws, their utility for homes is so limited that they aren’t worth the money. The phosphate-coated, coarse thread of one 1/4-inch or one 5/8-inch drywall screw works well for most tasks involving 1/2-inch drywall put on wood studs.
Because drywall installation necessitates many fasteners, this screw is affordable and available in large tubs. Shortening the length makes driving easier, but it also weakens the grip.
You might wish to use the longer drywall screw to hang drywall on ceilings. You can use either a long or short drywall screw to hang drywall on the walls.
The screw head’s bugle head alludes to its conical shape. This form makes it easier for the screw to stay in place without damaging the outer paper layer. The sharp point on some drywall screws is specified. The tip makes it easy to drive the screw into the drywall paper and start it.
Dry lining is a technique for attaching plasterboard to brickwork and masonry that includes applying dabs of plaster glue to the wall and then bedding the plasterboard on top.
