The Different Types of Screws: Which Do You Need?

Whether you are doing DIY repairs on your motorcycle or handling a complex woodworking project, you will need screws. But screws are not all equal, and they come in various types, making it challenging to decide the right option for your specific task.

If you’re a homeowner or a DIY enthusiast, knowing the different types of screws is valuable. And not just their names but also their application. In this article, we will look at the common types of screws so you can pick the right option for your project.

Machine Screws

Typically made from steel, machine screws are designed for fastening metal parts together. They are blunt-ended and require a pre-drilled hole or a nut for installation. Another distinguishing feature of machine screws is their diameter, which is consistent throughout their entire length.

According to the American Society of Mechanical Engineers (ASME), machine screws have a diameter of 0.75 inches or less. As a result, they’re generally smaller in size compared to most fasteners. Machine screws are available in different thread sizes, lengths, and head types, such as flat, round, or pan heads. They also come in different colours, from shiny grey to black screws. You can use machine screws in various applications, from fixing consumer appliances to electrical installation.

Wood Screws

If you’re making a piece of furniture, then you definitely need wood screws. These aren’t necessarily made from wood but are simply known as such because they are designed for attaching pieces of wood.

In fact, most wood screws are made of steel and feature coarse threads and a tapered head. This allows the screw to easily bite into the wood, pulling the two pieces as tightly as possible. On top of that, a wood screw feature a sharp point for digging into wood. But, like most other fasteners, wood screws need pilot holes to achieve their best holding strength.

Self-Tapping Screws

Self-tapping screws are an excellent choice for joining soft materials like plastic, wood, and sheet metal. They come with sharp self-drilling tips, eliminating the need for pre-drilling holes.

Since these screws create their own threads, they require minimal preparation for installation. This saves time, enabling you to complete your tasks faster. Another reason why you might like self-tapping screws is that they eliminate the need for additional tools and leave less residue to clean.

Sheet Metal Screws

As the name suggests, sheet metal screws are designed for fastening sheet metal. Unlike conventional screws with partially covered shanks, these screws feature full threads to increase retention between materials.

Sheet metal screws also have a sharp pointed end for digging into the material. However, this is not always possible, especially with standard sheet metal screws, and you might still need to pre-drill.

Masonry Screws

Masonry screws are your go-to solution for fastening stuff to concrete or block surfaces. They come with high-low and notched threads to help eliminate concrete shavings as you drive in the screw.

You can use masonry screws for ventilation systems, electrical installations, cable trays, fastening rails, and fences, among other applications.

Security Screws

Security screws are designed to prevent vandalism and feature special head types that are hard to remove with standard tools. Also referred to as tamper-proof screws, these unique fastenings are perfect if you’re worried about potential theft.

Drywall Screws

Drywall screws are used primarily for installing drywall panels and ceiling joists. Thanks to their sharp points and coarse threads, you can use them with wood or metal framing.

Drywall screws are excellent for home renovation and in-door DIY projects. Their bugle-shaped head sits flush with the surface of your drywall, minimizing damage and giving you a clean finish.

Until next time.
