How to measure a drill hole pich value

Question

Accepted Answer

The pitch value of a drill hole can be measured using a pitch gauge or by calculating the distance between consecutive threads.

Use a pitch gauge to directly measure the pitch value of the drill hole.
If a pitch gauge is not available, measure the distance between consecutive threads and calculate the pitch value using the formula: pitch = distance / number of threads.
Ensure accurate measurements by using precision tools and techniques.
Example: If the distance between two consecutive threads is 2 millimeters and there are 4 threads, the pitch value would be 0.5 millimeters.

Accepted Answer

Measure a hole value (example hole dia 10mm) divided by 2 and add pitch reference value (25mm),then you will get hole pitch (25+5=30mm)
