What do we call the center to center distance between holes along the same center line?

• A. Pitch
• B. Span
• C. Gap
• D. Run

Answer: (A)

Pitch is the distance from the center of one hole to the center of the next along the same centerline. This spacing defines how evenly the holes (or bolts, rivets) are laid out in a linear pattern, ensuring proper alignment with matching parts. Span refers to the overall distance between supports or ends, gap is the space between features without considering centers, and run usually describes travel length or extent of a cut or process. So the center-to-center spacing along the line is pitch.
