BOlT paTTErN

With the Machinist Calc Pro 2, you can determine a Bolt
Pattern by entering the Bolt Circle Diameter, the Number of
Bolt Holes and the Angle of the first bolt hole (optional). You
can also enter an optional center x and y-coordinate of the
Bolt Pattern.
In addition to calculating the x and y-coordinates for each bolt
hole, the Bolt Pattern function also calculates the hole center-
to-center spacing (i.e. On-center distance from hole to hole).
