Interpreting your results

After clicking ‘Calculate’, you will receive outputs such as bolt spacing, angle between bolts, and any other relevant figures. Understanding these outputs is critical for effective application:

• Bolt Spacing: Indicates how far apart the bolts should be positioned along the circle. For example, if your output indicates 90 degrees of separation for 4 bolts, you will space each bolt 90 degrees apart around the circle.
• Angle Between Bolts: The angle provides an easy visual guide. An output of 60 degrees for 6 bolts means you must set each bolt 60 degrees apart.

Who uses it

The Bolt Circle Calculator is an essential tool utilized across various industries and professions. Here are the key sectors and professionals that rely on this calculator:
