What are Hex Bolts?
Hex bolts are a type of threaded bolt that may be identified by the hexagonal form of their head, which has six sides. Both fully threaded and partially threaded hex bolts, with the clear shank across the entire body, have many uses and are widely employed in building and related industries.
You can pick the bolt that is most appropriate for the task at hand because there is such a wide range of options in terms of kind, material, size, and finish.
Due to the unique head form, hex bolts are also frequently referred to as hexagon bolts. Another name for hex bolts is hex head bolts. Hex head bolts are extremely flexible and adaptable fasteners, which enables them to be used for a wide variety of purposes across a wide variety of industries and applications.
Hex head screws for wood and metal, amongst many other materials and situations, are only one example of a common application for hex bolts.
They have excellent tensile qualities, and the majority of conventional types are versatile enough to be employed in a variety of settings depending upon the material and finish. As a direct consequence of this, hex bolts are one of the most common types of staple fasteners.
Where are Hex Bolts Used?
Here are some common uses of Hex bolts.
1. Construction Projects
Hex bolts are utilised in the construction industry for a variety of purposes, the most common of which is to establish joints between structural parts or to insert elements into a surface or substance.
Hex bolts are sometimes intended to be a permanent component of a building or other structure. This means that once they have been installed, they cannot be moved and do not require any additional maintenance or replacement.
2. Buildings, Bridge and Roads
Hex bolts are frequently utilised for projects involving wood, metal, and other types of construction materials. Examples of such projects include bridges, docks, buildings, and highway infrastructure.
They have excellent tensile qualities and can be utilised in a number of different contexts Hex bolts are put to use for applications that require heavy-duty fastening and fixing the majority of the time.
3. Machinery Assemblies
They are used to join two pieces of material together. However, unlike hex bolts, machine bolts do not have a chamfered point, nor are they built with a washer-bearing surface on the underside of the head of the bolt.
They normally come with options for both a hex head and a square head, but you can get them in either shape.
Recommended for structural connecting, including framing walls, due to their greater flexibility under pressure, in contrast to screws, which can snap under pressure.
In addition to this, you will need their assistance while installing hardwood flooring, fastening siding and roofing, and securing plywood sheathing used for the outside walls.
In most cases, hex bolts are utilised for the purpose of either positioning or holding materials or items together. The bolt is easier to put into nuts and holes thanks to the chamfer that is located on the other end of the head. This chamfer gives a slightly bevelled edge.
6. Vehicle and Automotive
The nuts and hex bolts are utilised in a variety of applications, including holding engine components, suspension arms, and dashboards in place. They are straightforward but indispensable, and millions of them are manufactured every day using a variety of iron and aluminium alloys.
How are Hex Bolts Manufactured?
The method of manufacturing
1. Cold Forging
The first step in cold forging involves taking massive steel wire rods, uncoiling them, and cutting them to the desired length.
The grade of steel used in manufacturing is standardised across the sector After that, the wire is cold-forged into the desired shape by utilising specialised apparatus. In this process, the steel is shaped while it is still at room temperature by passing it through a sequence of dies while the pressure is turned up to a very high level.
The tooling itself can be fairly complicated, with as many as 200 separate parts and tolerances that are measured in hundredths of a millimetre. As soon as it is developed, cold forging will ensure that bolts can be manufactured rapidly, in huge volumes, and with a high degree of consistency.
For more intricate bolt designs, which cannot be curved through cold forging alone, some additional turning or drilling may be required. This is because cold forging does not allow for the formation of rounded corners.
Turning requires spinning the bolt at a high speed while steel is sliced away to obtain the desired form and design.
Turning is also known as lathing. Drilling is a technique that can be utilised to create holes all the way through the bolt. At this point in the procedure, washers may be affixed to certain bolts in order to fulfil any prerequisites that may be necessary.
2. Heat Treatment
The act of subjecting a bolt to high temperatures in order to make the steel more resistant to wear and tear is known as heat treatment.
This technique is normal for all bolts. Typically, threading is accomplished before heat treatment, either by rolling or cutting the steel when it is in a more malleable state.
The process of rolling is quite similar to that of cold forging it entails passing the bolt through a die in order to form and shape the steel into threads. The process of cutting involves cutting and removing steel in order to make threads.
Because subjecting steel to heat treatment will cause it to undergo a transformation that will make it tougher, it is preferable and more economical to apply threading before subjecting the steel to heat treatment. Threading, on the other hand, should be done after heat treatment in order to achieve superior fatigue performance.
The heat treatment can leave the bolt with heat markings and even cause some small damage to it. "Because of this, certain customers require threading to be completed following heat treatment. This is especially true for applications involving engine and cylinder head bolts.
Because it requires the formation of hardened steel, the process is more expensive, but the threads will be able to keep their shape for a longer period of time.
3. Thread Rolling
After that, one of three distinct methods is utilised to cut the clear. During the subsequent pass, two level bites are used to cut the hex bolts. One of the dust bites is fixed, another one moves in a responsive manner, and the transparent screw is moved in between the two.
In order to construct the final string, the hex bolts clear to be replaced between several round passes while using a center tube shaped kick the bucket.
This is done so that the kick of the bucket may function properly. The inertial force imparted by a planet's rotation Last but not least, the string can be moved using the bucket cycle. It maintains a fixed position on the screw clear, allowing a few dust-cutting machines to move freely around the clear.
The heat treatment has the potential to have the effect of causing the steel to revert to the round shape of the original steel wire when it is applied to long bolts with a length that is more than ten times the diameter of the bolt. As a result, the application of a technique that straightens is frequently required.
The application of the bolt and the specifications of the customer are what guide the selection of the surface treatment. When it comes to fasteners, corrosion resistance is frequently the primary issue as a result, a zinc-plated coating that is applied by means of electrolytic treatment is a typical solution.
During this step of the process, the bolt is first immersed in a liquid that contains zinc, and then an electric current is passed through the liquid and the bolt in order to coat the bolt with zinc.
However, there is a higher chance of hydrogen embrittlement when the treatment is performed electrolytically.
Zinc flakes are yet another choice; despite their increased cost, they provide an even higher level of protection against corrosion.
Phosphate is a more cost-effective choice than other alternatives in situations where corrosion resistance is not a primary concern, such as inside an engine or in an application that is frequently subjected to oil.
After the application of the surface treatment, standard bolts are normally in a state where they are ready to be packaged. However, more complex designs may require additional assembly in the form of brackets or other components.
Patching will be necessary for the other bolts as well, either in the form of a locking patch or a liquid patch. A locking patch is constructed by layering a substantial amount of nylon over the threads in order to enhance grip. The thread-forming torque can be improved with the application of a liquid patch.
Features Of Hex Bolts
The feature of the hex bolt is to supply a clamp load, also known as a preload, in order to adequately compress and stress the gasket, as well as to withstand the separating forces that are caused by the hydrostatic end force and any other external stresses.
The pressure of the internal fluid exerted across the internal area of the flange contributes to the generation of the hydrostatic end force. In most cases, the internal area is equal to the diameter of the interior of the sealing element.
Every Hex bolt has the characteristics of a hefty spring. When you tighten the nut against the flange, the bolt lengthens, while the flange and the gasket are squeezed together.
There is no way of bolt-tightening that does not result in the bolt being stretched. In order to stretch the bolt, the torque-tightening method makes use of the thread helix created by twisting the nut in opposition to the reactive forces of the flange.
In order to achieve an axial stretch using the hydraulic hex bolt-tensioning method, an annular piston that is threaded on the end of the hex bolt is utilised. In the section titled "Methods of hex bolt Tightening," topics such as hydraulic bolt tensioning and torque tightening are explored. In the region of their elastic properties, hex bolts stretch in accordance with Hooke's law.
