Bolt torque chart is based on the component contained in the external thread or the material strength of the bolt.  Bolt Torque Chart Templates in word or excel format contains the size of bolt and the torque that is required to fasten it. The torque is recommended according to the grade of the material used and the bolt size.

Bolt torque calculator chart templates are available on this website and can be downloaded for free. You can print them and keep them for future reference. A specific bolt torque specification is based on several factors.

What Is The Importance Of A Bolt Torque Chart?

One may wonder as to why a bolt torque chart is needed. There are a number of varieties of bolts and torques available. The specification of each one could be different from the other. Thus it is important because it gives you the specific information about what sort of bolt needs which torque to fit properly. You can also see Baby Growth Chart Templates

For that you need to know more about bolts and torques, such as their size, class among other things. A chart can give you a complete list of the bolts and the torques. When you are using them for any machinery you need to know about their pairing.

What Are The Main Features Of A Bolt And Torque Chart?

The bolt and torque chart is used by an engineer, a mechanic etc., for making or fixing various machines. Not all bolts can be fixed with all types of torques, and therefore, knowing the specifications are necessary. Thus a good bolt and torque chart should have the important features of the bolts and torques, and preferably also which one suits the other.

Moreover, it might also be a good idea to describe the applications of the various types of the bolts, so that people can choose them according to their requirements. These are the main features of a bolt and torque chart. You can also see Element Chart Templates

How To Make A Bolt And Torque Chart?

There are a number of bolt and torque chart sample templates available in the internet. You can easily download them, as many of them are free, and use it for your needs. Other than that, making a bolt and torque chart following a sample found over the net is not a very difficult task. Make sure you have the specifications of the bolts and torques and then create a few column and rows, and tally them accordingly. Be careful about the measurements and the features you are using, and also put in the applications of the bolt in the chart.

Material Containing External and Internal Thread

  • The maximum force a material can bear before it undergoes permanent deformation is described as bolt proof load. A job will not get rejection letter if it fulfils this criteria.
  • The proof strength depends on the diameter and the grade of the fastener. In bolt torque chart templates grades are categorized into 2, 3, 5, 6, 7 and 8 and fine thread figures are from 1 to 14. Sizes from 4 to 10 are given in pounds per inch.
  • The proof strength of the nut needs to be greater or equal to the bolt’s tensile strength.

Thread Engagement and other Factors

Bolt Torque Charts from inspectors, proper fastener thread engagement is required along with the correct material strength of the nut and the bolt. Through bolt torque chart templates it is possible to determine bolt thread tensile strength area, nut “K” factor, bolt clamp pre-load force and can do various bolt torque calculations.

There are a number of bolt torque charts available on the net either in word format or in excel format. The relation of a bolt and torque is based on the material used in the external thread of the bolt or the bolt’s strength. The charts found in the internet are quite useful.
