How Important Is Bolt Tightening? Which Techniques Are Best?

Posted on

  • According to the fastener manufacturers, “When you are assembling your products with the help of either nut or the bolt, then you may find the process less tiring. But think about it again.

    If you will properly proofread the bolted connection then it may seem somewhat tiring to you. If the insufficient preload is applied, then it will result in the following:

    • Inaccurate tightening

    • Bolted Joint failure”

    How Should You Tighten A Bolt?

    Fasteners suppliers in Australia provide the fasteners based on the specifications of the tension and tensioning methods. The bolt is like a spring that generates and helps to make the preload be in the joint.

    How many kinds of tightening methods are there?

    The following are the various kinds of tightening methods:

    • Angle Tightening (Turn of Nut)

    • Tension Control Bolting

    • Torque Tightening

    • Direct Tension Indicators

    Which Is The Best And The Rightly Suitable Method For Tightening A Bolt?

    Different kinds of methods are considered preferable for their application.

    Here in this blog, we are going to mention the importance of the particular torque tensioning method.

    • Torque Tightening

    Torque is the kind of rotational stress which is applied to the bolt head so that the bolt gets threaded into the nuts and compresses the various plates of the joints. With the compression of the plates, the bolts get elongated.

    The torque which is applied should overcome the friction which generates the clamping force or load.

    Which tool should be used for torque tightening?

    The simplest tool which you can use is the clicker wrench. Based on your choice, you can use other kinds of electric, pneumatic and manual tools.

    • Direct Tension Indicators, Standard

    DTIs help you to get confirmed with the quantity of whether the tightened fasteners have generated the correct preload in the joint.

    The basic tools which will be required for it will be an indicator which allows you to use any type of tools that needs to be employed like the following:

    • Manual Wrenches

    • Pneumatic or Electric Torque Tools

    • Angle Tightening tools

    • Angle or Turn-of-Nut Method

    This method is super beneficial when you need a precise and accurate method that involves the structural bolts along with the constant preload. It can be used in several markets. The biggest one is – Automotive Manufacturing.

    That method is known for its two advantage:

    • Simplest tightening method

    • It allows you to make use of the multiple tool types that provide you with the clamp load that is not only effective but repeatable as well.

    • Structural Bolting

    The installation of these bolts is done with the unique electric shear wrench tool that does help to hold the nut when the tip of the bolt is getting rotated

    People usually find it difficult to find flaws in this technique of tensioning.
