Calculate bolt circle diameter (BCD) instantly. Enter number of holes and distance between them for accurate results. Perfect for engineering and automotive.
Calculate the diameter of a bolt circle based on the number of bolt holes and the distance between them.
Bolt Circle Diameter
0.00
Bolt Circle Diameter = Distance Between Holes / (2 * sin(π / Number of Holes))
Diameter = 10.00 / (2 * sin(π / 4)) = 0.00
