Introduction

Bolt tensioning and torquing are two different ways to adjust the tension on a bolt. Torque is the ability to apply a rotational force and is used to tighten and loosen bolts, while bolt tensioning is when the bolt’s nut is tightened against the head of the bolt. This tightening creates a drag on the bolt, increasing its stability and preventing it from loosening during use. Torque wrench use generally depends on the size of the bolt, while tensioners can be used with almost any bolt size.

What is bolt tensioning?

Bolt tensioning is the process of adjusting the tension on a nut or bolt by using a hydraulic press force. This is done to precisely adjust the strength of the connection between the parts being joined. The process can tighten or loosen connections, and it is an often-needed procedure in many industries. Hydraulic bolt tensioners are an essential part of modern machinery, as they allow for accurate and repeatable adjustment of bolt tension.

What is bolt torquing?

Bolt torquing is the act of tightening or loosening a bolt by turning it with a wrench. It’s an important part of industrial maintenance, and it can be done by hand or using a torque wrench. Torque is measured in foot-pounds, or Newton-meters (Nm).

To tighten a bolt, use enough torque to turn the bolt by 1/2 inch (13mm) in either direction. To loosen a bolt, use enough torque to turn the bolt by 1 inch (25mm) in either direction. Remember to always use the correct wrench for the job

What is the difference between bolt tensioning and torquing?

Torque is measured in Nm or ft-lbs, while tension is measured in pounds-ft. Bolt tensioning uses a slave screw to hold the bolt in place as the wheel is turned while torquing uses a wrench to turn the wheel. Torque values are higher for bolts that require more force to loosen, while tension values are higher for bolts that require less force to tighten. Torque values are used for bolts that require more force to tighten, while tension values are used for bolts that require less force to tighten. The bolt is tightened by pulling on it using a wrench, which can apply a load of up to 150 lbs-ft.

Pros and cons of bolt tensioning and torquing

There are pros and cons to both methods. Torquing can be more accurate, but it can also result in damage to the equipment if done incorrectly. Torquing also requires more time than bolt tensioning, which may be a drawback if you need to quickly fix something. Bolt tensioning is less destructive, but it can be less accurate and may require multiple attempts to get the correct torque setting.

Conclusion

Bolt tensioning and bolt torquing are two ways of securing bolts in place. They are both effective methods, but they have different pros and cons. Bolt tensioning is the process of applying a tension force to a bolt to keep it in place. This is done by tightening the nut on the bolt. The tension force keeps the bolt from loosening and coming loose.
