Understanding Your Bolt Torque Chart for 2023

What is a Bolt Torque Chart?

A bolt torque chart is a chart that lists the recommended torque for bolts of various sizes and thread pitches. The chart is based on a formula that takes into account the bolt’s material, size, and thread pitch. The chart is used to ensure that the torque applied to a bolt is sufficient to keep it secure in its assembly.

When do you Need a Bolt Torque Chart?

You will need a bolt torque chart whenever you are assembling a machine or structure that requires the use of bolts. The chart helps you determine the proper amount of torque to apply to the bolts. This is important because if you apply too little torque, the bolts may not be secure, and if you apply too much torque, you may strip the threads on the bolts.

Where Can I Find a Bolt Torque Chart?

You can find bolt torque charts in several places. The most common place to find them is in the manufacturer’s manual that came with the machine or structure you are assembling. You can also find them in online databases such as the Engineering Toolbox. Additionally, there are several websites that have downloadable bolt torque charts.

How to Read a Bolt Torque Chart?

Reading a bolt torque chart is not difficult once you understand how it is laid out. The chart will typically list the bolt diameter and thread pitch in columns, with the recommended torque in the third column. It is important to note that the chart is based on the bolt’s material, size, and thread pitch, so if any of these factors change, you should refer to a different chart.

Tips for Using a Bolt Torque Chart

When using a bolt torque chart, it is important to make sure that you are using the right chart for the bolts you are working with. Additionally, it is important to use a torque wrench when applying torque to the bolts. This will help ensure that the proper amount of torque is applied. Finally, always make sure to use the proper lubricant on the threads of the bolts. This will help prevent galling and ensure that the bolts are secure.
