What is the bolt angle of a flange that has 16 bolt holes?

The bolt angle of a flange with 16 bolt holes can be determined by dividing the full circle of 360 degrees by the number of bolt holes. In this case, with 16 bolt holes, the calculation would be:

360 degrees ÷ 16 bolt holes = 22.5 degrees per bolt hole.

This means that each bolt hole is positioned at an angle of 22.5 degrees from the next bolt hole, which is why 22.5 degrees is the correct answer. Understanding this concept is important in the design and installation of flanged connections, as it ensures proper alignment and even distribution of load across the flange.
