Industrial bolting is a crucial process in many industries that involves the tightening of bolts and nuts with the use of bolt tightening tools. This process is essential to ensure the safety, reliability, and functionality of industrial machinery and equipment. Industrial bolting might seem like a small and often overlooked process, but it can have significant effects on the overall performance of a machine.

The Significance of Proper Bolt Tightening

When bolts and nuts are not tightened properly, it can lead to serious safety issues, such as machine failure or breakdowns. To avoid these issues, technicians use controlled bolt tightening methods and equipment to achieve the required tension and torque specifications. Proper bolt tightening also helps reduce the risk of vibration-induced loosening, thread damage, and other mechanical issues that can lead to breakdowns and shutdowns.

The Impact of Industrial Bolting on Efficiency

The efficiency of industrial machinery depends on the installation and maintenance of its various components, including bolts and nuts. Improperly tightened bolts, worn-out bolts, or mismatched fasteners can lead to various issues, including machine downtime, decreased process efficiency, and increased maintenance costs. Industrial bolting helps maintain the integrity of the equipment and reduce failures that can lead to production downtime.

The Main Types of Industrial Bolting Tools

The right bolt tightening tool for a given job depends on factors such as the diameter, length, and material of the bolts, as well as the desired torque and tension specifications. Some of the most commonly used industrial bolting tools are:

Hydraulic Torque Wrenches (HTWs)

Hydraulic torque wrenches are reliable tools used for tightening large bolts and nuts in industrial settings. They apply a precise and uniform load on the entire length of a bolt, ensuring the correct tightening force across the joint. The hydraulic torque wrench is easy to use, lightweight and compact in size, making them ideal for confined spaces, and challenging installations.

Bolt Tensioners

Bolt tensioners are used to accurately measure bolt tension as it is being applied, ensuring that it falls within the desired specifications. The bolt tensioner applies a uniform load to the entire bolt shank, ensuring even surface pressure between the bolted members. This method of tensioning is more precise and safer than other methods of bolt tightening.

Battery-Powered Torque Wrenches

Battery-powered torque wrenches are used for tightening bolts in areas where access to air or electricity is limited. They are also ideal for outdoor applications. They offer a high degree of accuracy and are available in different models, including pistol grip and straight models.

Industrial Bolting Techniques for Better Efficiency

industrial-bolting,Industrial Bolting Techniques,thqIndustrialBoltingTechniques

There are different industrial bolting techniques that technicians use to fasten elements and parts together. The most common methods include the following:


Tensioning involves stretching a bolt to its elastic limit and then tightening it to the required specification. This technique offers accurate, consistent, and secure results as all the bolts experience the same tension. The technique is ideal for industrial applications that demand high preload and accuracy.


Torqueing is used to apply a precise amount of twisting force on a bolt to reach the required torque specification. The technique ensures consistent and accurate tightening of bolts. It is ideal for applications where there is minimal space or limited access to the fastener or limited time to complete the work.

Hydraulic Tensioning

Hydraulic tensioning involves using hydraulic pressure to stretch bolt to its elastic limit and then manipulating the pressure to the required preload level. This technique is best when handling large or critical applications that require high preload that cannot be achieved by other techniques, for example, machining, nuclear, and oil and gas applications.

Bolt Tightening

Bolt tightening is ideal for large applications, such as wind turbines and heavy machinery. This technique involves the use of hydraulic wrenches or impact wrenches to tighten bolts to the required torque specifications. It has become the most preferred method for most industrial applications that require accurate and fast tensioning without a compromise on safety.

Bolt Stretching

Bolt stretching involves stretching a bolt that is within its elastic range to reach a certain preload level. This technique is used in situations where access is difficult or where equipment has been worn out.

Bolt Tensioning and Torqueing

The technique involves applying tension and torque in a bolt at the same time. The method offers accurate and consistent results and is ideal for applications with high preload demands and limited access.

Bolt Loosening

Ease of dismantling and maintenance is important in industrial applications, and bolt loosening is necessary. Using impact wrenches, the bolt loosening technique loosens the bolt quickly and allows for easy dismantling.

Industrial Bolting Techniques

industrial-bolting,Industrial Bolting Techniques,thqIndustrialBoltingTechniques

Industrial bolting techniques are critical in ensuring that machinery and equipment are assembled efficiently and safely. The two primary industrial bolting techniques are torque tightening and tensioning. The most commonly used technique is torque tightening, which involves tightening the bolts to a predetermined value.

Torque Tightening

In torque tightening, the amount of torque applied to a fastener is used to achieve the desired tension. The technician uses a torque wrench to apply a specific amount of torque to the bolt or nut. The torque applied to the fastener results in the correct level of tension. Bolts that are not torqued correctly can lead to equipment damage, leakage, or failure.


Tension is an alternative industrial bolting technique to torque tightening. A hydraulic or pneumatic tensioning device is used to apply a specific force to the bolt. Tensioning is useful when the components are subjected to high loads or where the joints are under vibration. Tensioning provides a more accurate bolt preload; however, it can be more costly than torque tightening.

The Pros and Cons of Industrial Bolting Techniques

When considering which industrial bolting technique to use, there are pros and cons to each technique. Torque tightening is the most commonly used technique due to its low cost and easy implementation. However, torque tightening has its limitations for tight spaces. Tensioning provides a more accurate preload and is suitable for higher loads and vibration environments. However, due to the need for specialized equipment, tensioning can be more costly than torque tightening.
