Fastening Screws of Various Types

When you need a few hex set screws, you may have gone to a hardware store, where there are a thousand different sorts of screws in a variety of shapes and sizes.

Screws come in a variety of shapes and sizes depending on a variety of factors, including the application, the kind of head, the drive, and the threads. The kind of screw required is entirely determined by the material to which it will be attached. Using the proper screw will help you prevent problems like screw head breaking, loose screws, and material tearing up, while also increasing the screw’s dependability.

So, let’s take a look at some of the most popular screw kinds and what they’re best used for.

Wood Screws 

These screws, as the name implies, are used to attach wood to each other. Brass, bronze, and steel are the most common metals used in wood screws. As we approach the head, the point’s shank becomes larger and thicker and broader and typically has an unthreaded shank at the top. The unthreaded shank half of this basic wood screw must thus be pre-drilled into the material before it can be used.

Some woodscrews feature-complete thread shanks, which means they don’t need to drill a pilot hole since the diameter is the same from the end of the head to the tip of the screw. When it comes to the application’s “head,” it all depends on what you’re applying for. Flathead screws may be used if the screw is to be flush with the surface, although round or oval woodscrews can be used for decoration. For softwoods, coarse screws have fewer threads, whereas fine screws have more threads, and they are utilised in the same applications as coarse screws in the first place.

Drywall Screws 

hex set screws  that have a bugle head protect the finish by preventing the surface from ripping. For the most part, drywall screws are categorised into two groups based on their length and pitch. With a high pitch and length, (W-Type) is used for fixing drywall with softwoods.

The other is (S-type), which is short in length and pitch and finely threaded for attaching drywall to hardwood or metal studs. The self-drilling tip with fine threads eliminates the need for a pilot hole or pre-drill hole. To avoid breaking up the material, a fast-moving screw is needed.

Deck Screws 

Similar to collated drywall screws, but with greater corrosion resistance coatings, such as zinc plating galvanised, ceramic coating, and so on, these screws are superior. To resist the severe conditions of the outdoors, these screws are designed specifically for wood decks. The countersunk head of the composite deck screws ensures that they sit flush with the deck surface. To eliminate pre-drilling pilot holes, they are commonly provided with sharp edges and narrow points.

Sheetmetal Screws 

A variety of materials may be attached to metal, including wood, plastic, and metal-on-metal joints. Their diverse head designs, including flat, oval, truss, pan, hex, and others, allow them to be used in a wide range of applications, and their threaded shanks allow them to penetrate any hard material or metal. In general, sheet metal screws come in two varieties: those that need pre-drilling before penetrating the material and those that have a drill-like form on the tip of the screw itself.

Screw Fixings in Brief 

Mild steel hex set screws are the most common kind, although stainless steel and brass are also available. Additionally, they might be zinc, chrome, or brass-plated.

Screws, unlike nails, must be screwed into place using a screwdriver. This is why they are available in a variety of head shapes and materials, including slotted, cross-head (Phillips), and others.  Small screws may be preferred over nails when it comes to securing things together or affixing objects to a wall since they may be removed and reinstalled similarly to how they were installed.

Rawl plugs are necessary for usage in masonry walls, whether they are made of masonry or concrete, to provide a greater grip on the material. When using this method, screws are placed into a rawl plug (typically plastic) rather than the wall itself. These may be made of plastic or fibre, depending on your preference.

Masonry nails may also be used to fasten wall linings and skirting boards with expansion sleeves. When screws are used with an adhesive in woodwork, there is typically no need to hold the two parts together as there would be if just an adhesive were employed.
