## What is the proper torque to use on a given bolt?

The first factor is the bolt’s diameter. It takes more force to tighten a 3/4-10 bolt than to tighten a 318-16 bolt because it is larger in diameter. The second factor is the bolt’s grade.

What is the Proper Torque to Use on a Given Bolt. by Joe Greenslade.

Product: 3/4-10 Grade 5 zinc plated bolt
• P= 23.046 pounds

## What is torque of bolt?

Torque is a “turning” or “twisting” force and differs from tension, which is created by a straight pull. However, we use torque to create a tension. HOW? … The thread angle in the bolt converts the force applied into tension (or stretch) in the bolt shank. The amount of the tension created in the bolt is critical.

## How tight should bolts be?

In general, you should make the bolt tight enough so that the items it is holding together stay together, but not so tight that you damage the bolt’s threads. You should tighten bolts properly so that the bolt performs properly.

## How do I know how much torque I need?

Torque is defined the length of the lever arm multiplied by the force applied. For instance, if you have a two-foot long bar and you hang a 10-pound weight from it, you have 20 foot/pounds of torque.

## Why do bolts have torque settings?

Torque is used to create tension. Bolts are used to affix two components so that they can resist tensile (pulling apart) and shearing (sliding apart) forces. After the nut has been turned onto the bolt, additional torque causes the nut to turn and stretch the bolt.

## How do you calculate max torque on a bolt?

You may determine the maximum, or max, torque for a screw with the mathematical formula T = K x D x P. The formula’s “T” is the targeted torque for the screw measured in inch pounds.
