A bolt circle diameter or pitch circle diameter (PCD), sometimes simply called bolt circle or pitch circle, is a common term for when a number of screw holes for bolts are evenly distributed with their centers along an imaginary circle with a given diameter.
The Pitch Circle Diameter (PCD) is the diameter of that circle that passes through the center of all the bolt holes or wheel bolts or wheel rim holes or studs. The best example is Flanges, there are multiple holes in the Flanges, the circle through the center of these holes is known as the pitch circle, and the diameter of this circle is known ...
The bolt circle's measurement is called the bolt circle diameter (BCD), [3] also called the pitch circle diameter (PCD). [4] The bolt circle diameter is typically expressed in mm and accompanies the number of bolts in your vehicle's bolt pattern. One example of a common bolt pattern is 5x100 mm.
The holes on the spider arms used for attaching a chainring can have a variety of spacings, referred to as the bolt circle diameter, commonly abbreviated as BCD. This measurement is sometimes referred to as pitch-circle diameter (PCD). Cranks designed to mount one or two chainrings will almost always use a single bolt circle diameter.
A pitch circle (operating) is the curve of intersection of a pitch surface of revolution and a plane of rotation. It is the imaginary circle that rolls without slipping with a pitch circle of a mating gear. [1] These are the outlines of mating gears. Many important measurements are taken on and from this circle.

A de facto industry standard among sim wheels, which again stems from a widely used mechanical industry standard, is a front mount with a bolt circle measuring 4×130 mm diameter and metric M8 screws, which means that four screws are evenly placed along a circle measuring 130 mm in diameter.
