How to Use the Calculator

The calculator has two modes: Basic and Advanced.

1. Basic Calculator

  1. Enter Bolt Diameter (in): Type the diameter of the bolt. For example, enter 0.5.
  2. Enter Threads per Inch: Input the number of threads per inch. For example, enter 20.
  3. Calculate Bolt Area (in²): Click “Calculate” to find the missing value.

2. Advanced Calculator

  1. Enter Bolt Diameter 1 (in): Input the first bolt’s diameter. Example: 0.5.
  2. Enter Threads per Inch 1: Input the threads per inch for the first bolt. Example: 20.
  3. Enter Bolt Diameter 2 (in): Input the second bolt’s diameter. Example: 0.6.
  4. Enter Threads per Inch 2: Input the threads per inch for the second bolt. Example: 18.
  5. Calculate Combined Bolt Area (in²): Click “Calculate” to find the combined area.

What is the Bolt Area Calculator?

The Bolt Area Calculator is a tool used to calculate the cross-sectional area of a bolt. This is important for understanding the bolt’s strength and load-bearing capacity.

Formula

The formula to calculate the bolt area is:

BA=0.7854×[D(0.9734n)]2

Variables

Variable Description
BA Bolt Area (in²)
D Bolt Diameter (in)
n Threads per Inch

How To Calculate Area Of A Bolt

Example 1

Input: 

  • Diameter = 0.5 in,
  • Threads = 20

Calculation:

Use the formula:

BA=0.7854×[0.5(0.973420)]2

1: Calculate

0.973420=0.04867

2: Subtract from Diameter:

0.50.04867=0.45133

3: Square the result:

0.451332=0.203

4: Multiply by 0.7854:

0.7854×0.2037=0.1599

Result: Bolt Area = 0.1599 in²

Example 2

Input: 

  • Diameter = 0.75 in,
  • Threads = 16

Calculation:

Use the formula:

BA=0.7854×[0.75(0.973416)]2

Step 1: Calculate

0.973416=0.06084

Step 2: Subtract from Diameter:

0.750.06084=0.68916

Step 3: Square the result:

0.689162=0.4749

Step 4: Multiply by 0.7854:

0.7854×0.4749=0.3730

Result: Bolt Area = 0.3730 in²

I hope you found above steps helpful, you can calculate the bolt area accurately. Use the calculator to save time and ensure precision in your calculations.
