Things to Consider When Purchasing hex nuts and bolts

Different types of industrial fasteners are available in the market for a variety of applications though they have the identical function of holding parts and components together. The fasteners family is pretty large with a member like nuts, bolts, screws, pins, washers, rivets etc. Within this family hex bolts and hex nuts, hex screws, and hex head screws enjoy a special place. Machined threads and hexagonal heads are the key distinguishing characteristics of hex nuts and bolts. Hex bolts and nuts are used frequently in woodworking, steel and other construction jobs like buildings and bridges.

Understanding hex bolts

Before examining a buying guide for hex bolts and nuts, let us examine a brief description of this fastener.

Definition of hex bolts

Many bolts and screws are identified by the driving style and hex bolts are distinct on account of the six-sided head (hexagonal) head they have. This bolt style is also the industry standard for different fasteners having forged heads. Though most hex bolts are threaded partially, for specific applications you can also find fully threaded hex bolts.

Benefits of using hex bolts

The wider application of Hex bolts is in the engineering and construction industry irrespective of whether they are fixed on different materials or in the same building or distinct projects within the same site. Hex bolts are so versatile that they find convenient application in a variety of settings. The hexagonal head makes it convenient to use with gripping tools from multiple angles and easy to grab by hand too. This makes it very convenient to tighten or loosen since the tools can be used in different directions. Hex bolts are manufactured to comply with tensile specifications and environmental demands.

Using hex bolts

Hex bolts are particularly useful in infrastructure projects that need strong fasteners having high tensile strength due to the base materials and design. These projects generally present several tight spaces and limited access to work with. In these situations, the ability to use tools to tighten or loosen the bolts at different angles is very important and the hex bolts with 6 different points of contact on the head present the much-needed flexibility. Offered in varying thread styles, lengths and finishes, they are very convenient in fastening steel, wood and other materials employed in construction and can therefore be deployed seamlessly on site. Buildings, highway structures, bridges, and docks are typical application areas for hex bolts. Fastener design, diverse application and number of variants make hex bolts a staple for many industries across the globe.

Thread

Hex bolts are also offered with different types of thread to address the end-user needs. Generally, such specialized threading is essential in heavy-duty applications.

Fully threaded

Fully threaded hex bolts are also called ‘hex sets’ and the threading is done right up to the head of the bolt making them a great option for use with pre-threaded holes. A fully threaded hex bolt is an excellent fastening solution in applications that are focused on the grip and lesser importance to shear strength and alignment. Once applied, the hex bolt spreads the pressure throughout its length with the highest pressure on the head.

Plain/partial threading

Plain hex bolts are offered with an unthreaded shank below the head of the bolt. This style is highly suitable for alignment and resistance. In projects needing plenty of force to hold objects in place, partially threaded bolts the desired strength. The segment of the bolt with no threading is at times called grip length. When the portion of the bolt with no threading is inserted into a hole with the correct size, it delivers perfecting fastening resistant to shear forces and vibration.

On that note, here is your guide to buying hex bolts and nuts

Bolt type

There are certain industrial applications wherein hex bolts are considered ideal. But, for many other applications hex nuts and hex bolts are not just suitable. Conversely, foundation, stud, anchor or carriage could have been a better choice for a wide array of applications. Therefore, before choosing hex bolts, you should consider the condition and purpose of your application and match it with fasteners that have the right size, material and design.

Bolt material

Though you can buy hex bolts made out of a preferred material, you cannot side-step assessing the properties of the chosen material and their impact on the structures or objects where the hex bolt will be used. Brass, steel and alloy are typically the material employed in manufacturing hex bolt but these materials also branch out into distinct classifications and each of those classifications works under defined conditions. Therefore, when you are shopping for a hex bolt, it is important that you choose the closest or exact material class that suits the intended application or end-use.

Size

After choosing the material, the next important consideration is the size of the bolt. Normally Hex bolts are offered in varying designs and sizes. For certain applications custom sizes are also preferred to allow perfect fitting. Generally, you should invariably assess the size of the bolt for your specific application so that you are not burdened with hex bolts that cannot hold the objects that you need to hold together.

Application

As we have learned earlier, the application for which you are choosing hex bolts will guide you to determine the right bolt. Irrespective of whether the application is in construction, machinery or other areas the hex bolt chosen must match the application seamlessly without room for malfunction or failure. The hex bolts chosen should also withstand external conditions to help them last longer. Usually, hex bolts are manufactured for varying specifications to meet specific applications.

Conclusion

Going through a short learning curve to understand different types of hex bolts and aligning the findings with your specific needs will ensure that you are shopping for the right product.
