M16 Metric Thread Dimensions and Pitch
Below are the key dimensions for M16 metric threads: pitch, tap drill and clearance drill according to ISO 724:2023.
M16 Coarse (standard)
Welcome to our M16 Metric Thread Page, your go-to resource for swift measurements on M16 metric threads. We've gathered an expansive library of data for all standard metric threads you'll utilise in your parts, highlighting important dimensions like thread pitch, tap drill, and clearance drill. This page is a complete solution for engineers, machinists, and hobbyists seeking reliable and precise data.
M16 Coarse Pitch Dimensions

All dimensions stated in are mm (millimetre)
ISO Metric Thread profile
The Major Diameter is the largest diameter on the thread and is measured from the thread crest to crest (peak of the thread).
This is the distance (mm) from one thread to the next, this can be measured from tip to tip or groove to groove. Pitch can also be defined as TPI, which stands for threads per inch.
Minor Diameter is the smallest diameter on the thread and is measured from the thread root to root (Bottom of the thread).
The angle between the thread faces. 60 degrees in the example above.
The thread will assemble when rotated clockwise. "righty tighty lefty loosely"
The thread will assemble when rotated counter-clockwise.
