Frequently Asked Questions
How is the distance between bolt holes calculated?
Holes evenly spaced on a circle form a regular polygon. The straight-line distance between two adjacent holes is the bolt circle diameter times the sine of 180 degrees divided by the number of holes.
Are the holes assumed to be perfectly evenly spaced?
Yes, this calculator assumes a standard uniform bolt circle pattern with equal angular spacing between all holes.
Can I use this for a flange or wheel bolt pattern?
Yes, this is the same geometry used for flange bolt patterns, wheel lug patterns, and any circular array of evenly spaced holes.
