Bolt Circle Calculator

How to Use the Bolt Circle Calculator

This Bolt Circle Calculator allows you to determine the precise positions and spacing of bolts on a circular pattern. Follow these steps to ensure accurate calculations.

Step 1: Provide Essential Inputs

• Bolt Circle Diameter:

  Enter the diameter of the bolt circle in the designated field. This value must be a valid number greater than or equal to 0.1. Use increments as small as 0.001 for precision.

• Number of Bolts:

  Specify the total number of bolts you plan to distribute around the circle. Ensure the number lies between the minimum of 2 and a maximum of 360, ensuring each entry increment by steps of 1.

• Start Angle:

  Input the starting angle in degrees where the first bolt will be placed. This angle must be between 0 and 360 degrees with steps as precise as 0.1 degrees.

Step 2: Calculate Results

Upon entering all required inputs, the calculator will compute the following:

• Angle Between Bolts:

  This value is calculated by dividing 360 degrees by the number of bolts to determine the angular spacing. The result will be presented in degrees formatted to two decimal places.

• Bolt Circle Radius:

  The calculator will halve the bolt circle diameter to determine the radius, presenting this measurement with three decimal precision.

• X Coordinates:

  Using trigonometric calculations, this value determines the X-axis position for each bolt based on its angular displacement. The results will show coordinates formatted to three decimal places.

• Y Coordinates:

  Similarly, this computes the Y-axis position for each bolt. It applies trigonometric sine functions to derive coordinates, formatted to three decimal places as well.

• Bolt Spacing (Chord Length):

  The calculator will determine the chord or straight-line distance between two adjacent bolts. Results will be presented with accuracy to three decimal places.

Step 3: Review and Apply Results

With the calculated values, you can accurately position the bolts on the circular pattern. Utilize the X and Y coordinates for precise placement, and the bolt spacing information to ensure even distribution across the circle. This ensures a balanced and effective application of the bolt circle configuration.
