Properties and Benefits of Bolts and Screws

Bolt and Screw Overview: Find Major Differences and Benefits

Screws and bolts refer to similar fastening hardware because they look similar and have the same characteristics. In fact, these are two different fasteners with their exclusive uses. For this reason, it is significant to understand the difference between bolt and screw.

Bolts are useful for the assembly of unthreaded objects with the help of one nut. On the other hand, screws are important to assemble different objects containing threads. Remember, you may not find a thread on every screw. Some things feature pre-made threads, and others may create thread during screw installation. 

For this reason, the main difference between bolts and screws is their uses. The former is suitable for the assembly of unthreaded objects. Meanwhile, other is important for the assembly of threaded objects. Screws may make their threads during an installation procedure.

It does not matter if screws should be turned for a joint assembly. You can use a carriage bolt or tool to secure the bolt in the right place. Remember, bolts are useful for bolted joints with a nut to use shank for force application that works as dowels. You can pin joints against sideways forces. Several bolts come with an unthreaded shank or a grip length; therefore, these are efficient for dowels.

Types of Bolts and Screws

You will find different types of bolt screw, such as arbor bolts, hanger bolts, anchor bolts, hex bolts, elevator bolts, rock bolts, lag bolts, J bolts, hanger bolts, U bolts and shoulder bolts. Moreover, these are available in different materials, such as stainless steel, nylon, brass, steel and bronze. To meet the needs of manufacturing companies, maximum bolts are designed with steel.

Similarly, there are different screw types, such as particleboard screws, drive screws, deck screws, eye screws, drywall screws, hammer drive screws, twin fast screws, wood screws, sheet metal screws and security head screws. Some head shapes for screws are round, button, pan, cheese, flanged, fillister, bulge, oval and mushroom. Just like bolts, screws are available in different materials.

Screws and Bolts: Explore Functional Differences

A screw is installed in a tapped hole if you have a self-taping screw. This type of screw can create its thread. Remember, screws may not need nuts because they become secure once you make them tight in the hole using a driver or screwdriver. It can fit perfectly in a drive recess. In general, screws may be short as compared to the material width to be screwed in. For this reason, you will not see them protrude on the opposite side.

Bolts Work with Suitable Nuts

The hole for bolts may not be tapped because the bolt is fixed after pushing through and tightened with a nut at the material back being fastened. Your bolt can be longer as compared to the material width it will be used on. It should protrude through the other side of the screw in a nut. 

Remember, unthreaded bolt portion will sit in the material to increase strength and increase its resistance to shear forces. Bolts are fastened with a spanner or any other tool to grip the head while tightening the nut. Moreover, you can use bolts similar to screws if bolts are installed into threaded elements. Fully threaded bolts or set screws are available for use. After this explanation, bolt vs screw will be an easy comparison for you.

Screws and Bolts for Security Uses

Their applications mainly determine the design of the screws and bolts. Remember, security is an essential factor. For instance, shear bolts are suitable if fixing is free from the hazard of removal. A shear bolt comes with a snap-off head, leaving a plain head without any drive for bolt removal.

If fixing is removable, the head will become an essential factor because the drive helpful to remove and fix must not be available easily. Bits of security driver is available that can be matched to the security screw head. It is necessary to decrease the chances of unauthorized tampering.

Advantages of Bolts and Screws 

For the bolt vs screw debate, it will be good to learn about its advantages and disadvantages. Remember, they are created for different materials and applications.


If you need a versatile fastener, you will need screws. They offer a secure grip because of their thread and meet the needs of DIY projects. You will get them in different types and sizes for drywall, metal, and wood. Moreover, special screws are available for concrete projects.

These are self-tapping, but you can drill one pilot hole in some cases. To save time, feel free to drill all pilot holes at the same time. To secure screws, you can use power drills easily available in the market. With the help of a drill, it will be easy to remove or install screws.


Bolts are suitable for their holding strength as compared to screws and different other fasteners. Threads in bolts can offer an excellent holding powder. They may need a washer or a nut for installation. With the help of a washer, you can spread the load on a huge surface area. As a result, you can decrease wear and tear and loosening of the bolt with time. Remember, nuts will secure the bolts to their place.

Just like screws, you will get bolts in different types and sizes. You can use them with other materials, such as wood, concrete and metal. If you want to install bolts, make sure to arrange a pneumatic or handheld wrench. As compared to screws, it is easy to remove bolts. 

Applications to Choose Between Screws and Bolts

Before selecting a screw or a bolt for your upcoming project, you must focus on some crucial factors.

Your project will be an essential factor to decide between screws and bolts. If you need better holding strength, you can choose bolts. Remember, the holding power of screws is less than bolts. For light and medium projects, you will need screws for framing and fencing. Make sure to choose bolts for heavy-duty projects. 

Material is another factor to choose between screws and bolts. Plywood, drywall, deck planks, sheet metal and pressboard need screws. On the other hand, beams, studs, and concrete need bolts.
