Screws vs Bolts – What’s the Difference ?

screw and bolts

When you’re putting together a project, whether a DIY project or a professional one, selecting the right fastener is essential to ensure its longevity and stability. And this is where screws and bolts come into play. Both screws and bolts are very similar, but they work differently. While both are used to fasten materials together, they have different functions and strengths. So, in this blog post, we’ll look at screws and bolts and help you decide which one you should use.


What are Screws ?

Screws are fasteners designed to be inserted into pre-drilled holes and fasten two or more materials together by creating a tight bond. Screws come in various lengths, diameters, heads, and materials, making them suitable for various applications. They are commonly used to attach wood, metal, and other materials, with some types of screws being ideal for specific applications.

What are Bolts ?

Bolts are also fasteners that are used to secure materials together. Unlike screws, bolts are longer and have a shaft that threads directly into the material or is inserted through one object and threaded into another. Bolts also come in various lengths, diameters, and materials, making them suitable for many applications. One of the key features of bolts is that they can handle higher loads than screws.

Difference Between Screws and Bolts

A screw is a type of fastener that is used to join two pieces of material together. A bolt is also a type of fastener, but it is slightly different than a screw. Both screws and bolts are made from metal, and they are both used to join two pieces of metal together. However, the main difference between a screw and a bolt is that a screw is designed to be inserted into pre-drilled holes, while a bolt is designed to be inserted into a nut.


One of the main advantages of using screws is that they create strong and durable connections that are hard to loosen. The threads on the screw shaft grip the material so tightly that they keep it in place. This makes screws the perfect fastener for heavy-duty and structural applications requiring a tight fit. Moreover, screws are easy to remove if needed, which is useful when disassembling the project or making changes.

Bolts are stronger than screws because they distribute the weight across a larger surface area, making them suitable for applications that require more significant structural support. In addition, bolts can be tightened using a nut and washer, which increases the clamping force and ensures a stronger bond. On the downside, bolts require drilling through the material, which takes longer and is harder than merely drilling a hole to insert a screw.


One disadvantage of using screws or bolts is that they can become loose over time. This can be due to wear and tear, vibrations, or even changes in temperature. Another disadvantage of using screws or bolts is that they can be difficult to remove once they have been installed. This can be especially true if the screws or bolts have been installed in a hard-to-reach location


If you use screws or bolts, the idea is the key element in this. Remember: the bolts have a huge amount of holding power while the screws have a middle ground for holding power. Light to medium construction projects are best for screws, for example for fencing or framing. The bolts are perfect for your heavy-duty designs. Also, bolts work better where the completed product is designed to be quickly installed and disassembled. When deciding whether to use screws or bolts, the material you are fastening, the application, and the loads your project will encounter should be considered. Screws work best for lightweight applications, such as attaching curtain rails, joining small pieces of wood or metal, and other DIY projects that don’t require a lot of strength. On the other hand, bolts are ideal when your project requires structural stability and support, such as building a deck, securing machinery, or joining metals that will undergo significant stress.


Cost is often a consideration when budgeting a project, particularly if a large number of fasteners are needed. Although using bolts may be more expensive, you’ll save money in the long term by choosing the right fastener. If you end up having to do repairs on the project because you used the wrong fastener for the material or application, by going the cheaper route you are not actually saving any money.

How are screws and bolts made?

Screws and bolts are both made from metal. The first step in making either one is to create a mold of the desired shape. Once the mold has been created, molten metal is poured into it and allowed to cool. Once the metal has cooled, the mold is broken away, revealing the finished product.



Choosing between screws and bolts can be challenging, but making the right decision for your project can ensure its success. For lightweight applications, screws offer speed, simplicity, and convenience. On the other hand, bolts provide the strength, durability, and structural stability needed for heavy-duty applications. Ultimately, the choice between screws or bolts will depend on your application and the loads it will encounter.
